What Happens When the Electrical Activity of Your Heart Changes?

The heart's electrical conduction system plays a very important role in cardiovascular functioning. Also known as the atrioventricular (AV) conduction system, it regulates and controls the timing of the heartbeat.

How does the heart's electrical conduction system work?

There is a collection of electrical cells in the upper right atrium of the heart known as the sinoatrial (SA) node which acts as a natural pacemaker and generates electrical signals. These signals travel through specialized electrical pathways and stimulate the muscular walls of the heart to contract in a rhythmic manner. This gives rise to the heartbeat that pulses at a specific frequency every minute.

What is the effect of fluctuations in electrical activity on the heart?

The standard heart rate in human being ranges from 60 to 100 beats per minute. It slows down when a person sleeps and speeds up when one experiences physical or emotional heightening. These fluctuations are triggered by the brain or other systems of the body and signal the SA node to generate charges more rapidly or slowly. This leads to spikes and drops in the heart rate, depending on the nature of the situation.

What happens when there is dysfunction in the heart's electrical activity?

When the heart's electrical conduction system does not function properly, it leads to the occurrence of a condition known as arrhythmia or abnormal heart rhythm. This happens when electrical impulses are generated in an irregular manner and causes tachycardia (rapid heartbeats) or bradycardia (slow heartbeats) which takes place in jarring infrequent tempos.

What causes fluctuations in the heart's electrical activity?

There are various kinds of triggers that cause the heart rate to fluctuate. The exact nature of fluctuation also depends on the type of trigger. A few everyday examples of these causes are as follows:
- Exercise and strenuous physical activity increases electrical activity as the heart is required to beat faster so as to increase the supply of blood and oxygen to the muscles.
- Sleep and rest reduce heart rate as the body is not needed to exert itself.
- Release of adrenaline into the bloodstream causes the heart rate to spike up.

What is Palpitation?
Palpitation is a feeling of awareness of your own heart beat. It is usually described as heart rate being either too fast (racing), too slow or a sensation of missing a beat.

Types of palpitations?
Normal (Benign)
- These palpitations occur as a response to physical or mental stress like exercise, fever, pain, fear, anxiety etc. 
- They are harmless and settle on their own once the precipitating factors disappear. They do not require any medical treatment.

Abnormal
- These palpitations occur due to some underlying abnormality in either the structure of heart or the beating of heart. 
- These can be dangerous and at times life threatening. They may or may not settle on their own and require some medical treatment.

Warning signs that suggest palpitations are abnormal?
Palpitations are abnormal, if they are associated with chest heaviness, chest pain, uneasiness, sweating, weakness, giddiness, feeling of black out, fainting, nausea, vomiting, seizures. Palpitations are more likely to be abnormal in people who have some existing heart disease and these patients should report to their doctor at the earliest.

What to do during palpitations?
1. Stay calm. 
2. Call for help. If u are alone avoid driving, use a taxi or auto, go to your nearest hospital/doctor and try to get an ECG during the palpitations. If you are helping someone having palpitations, if they faint, call for help, start CPR if they remain unresponsive and take them to the nearest hospital. 

Which doctor can treat palpitations?
Doctors who specialise in the treatment of palpitations are called Electrophysiologists. They specialise in heart rhythm and are capable of performing a variety of complex tests to identify and treat different types of palpitations.

Which investigations are used to diagnose palpitations?
ECG: Taken during palpitations and when the patient is normal is a very helpful tool. 
Holter: Externally applied recorder, which continuously records heart rhythm for 24 hrs. 
ELR: Extended loop recorder, is like holter, but it records rhythm for longer durations. 
ILR:  Internal loop recorder is attached within the body for recording rhythm for long duration. 
EPS: Electrophysiology study, is the most sure shot test to diagnose, identify and treat 
Palpitations.

What is EPS?
EPS stands for Electrophysiology study. By this test a trained Electrophysiologist studies the conduction and formation system of heart beat, to understand the source, cause and type of palpitation. It is a simple and safe procedure of 2 to 3 hours and can be done as a day care procedure (by admitting the patient for a few hours in hospital, with discharge on same day).

It requires fasting for 4 hrs, some standard blood investigations and is done with local anaesthesia and if required it can be combined with treatment like ablation in the same sitting.In the procedure Electrophysiologist take catheters into your heart to study and stimulate the palpitations and understand them. Once found they can use various techniques to stop the palpitations, the techniques are called Ablation.

What are the treatment options available for palpitations?
There are many options depending upon the nature of palpitations and condition of the patient: 
- Drug therapy 
- Cardioversion where either a drug or electric shock is given to stop palpitations immediately. 

Ablations using many sophisticated computer softwares 
Device Therapy like ICD (Internal cardiac defibrillator) 
Combination of all the above therapies.

Your Electrophysiologist and you as a team can make a choice about the options that will be best for you.

Palpitations - Everything You Need to Know

Homeopathy is a method of treatment, which is based on the fact that symptoms of a certain disease, if induced in small quantities, may help cure the same disease in a sick person. Cardiological disorders are complications of the heart; they can range from various disorders, such as heart attack or irregular heartbeats.

Homeopathic remedies are based on naturally occurring substances and are given to the patients in a diluted form. These remedies trigger the symptoms in small quantities and heal the body.

The various homeopathic treatments for cardiological disorders are:
1. Latrodectus: This treatment is used to treat symptoms of precordial pain in the body.

2. Aurum metallicum: Aurum metallicum is used in treating symptoms of weakness in the muscles of the heart.

3. Aconitum:This treatment is used when a person is having a heart attack.

4. Spigelia: Spigelia is used in the treatment of irregular heartbeats which may cause sharp pain in the chest.

5. Cactus grandiflorus: This treatment is used in treating angina pectoris, which is characterized by symptoms of pain caused by decreased blood flow to the heart.

6. Crataegus oxyacantha: This homeopathic treatment is used in treating coronary insufficiency in people. This disorder cause problems in heartbeat.

7. Digitalis: This homeopathic treatment is used in treating cardiac muscle failure. This disorder causes palpitation, tightness in the heart muscles and a suffocating sensation.

8. Kalmia latifolia: This treatment is effective in treating cardiac hypertrophy, which causes the heart muscle to thicken, resulting in size reduction of the ventricles. This treatment is very effective in treating cardiac hypertrophy that results after rheumatism.

9. Glonoinum: This homeopathic treatment is prescribed to treat symptoms of plaque buildup in the artery, which cause hypertension.

Some foods punch well above their weight in helping to reduce cholesterol levels, we call them'cholesterol busters. Choosing a healthy diet, low in saturated fat is important in helping to keep your cholesterol low but you can reduce your cholesterol levels further by including these super six foods in your everyday diet.

Super food 1 - soya foods
Being naturally low in saturated fat, soya foods help lower cholesterol. The special proteins in soya also appear to influence how the body regulates cholesterol too. Studies show you can lower your cholesterol by around 6% by including as little as 15g soya protein per day.

Choose from: soya alternatives to milk and yogurt, soya desserts, soya meat alternatives, soya nuts, edamame beans and tofu.

Super food 2 - nuts
All nuts are rich in vegetable protein, fibre, heart healthy unsaturated fats, vitamin e, magnesium, potassium, natural plant sterols and a host of beneficial plant nutrients. 30-35g a day of nuts (a handful) has the potential to lower cholesterol by an average of 5%.

Super food 3 - oats and barley
Both oats and barley are rich in a form of soluble fibre called beta glucan. Once eaten beta glucan forms a gel which helps bind cholesterol in the intestines and prevent it from being absorbed. It is recommended that we eat about 3g of beta glucan per day. Foods which contain 1g or more of beta glucan can carry a cholesterol lowering claim.

Super food 4 -foods fortified with plant sterols and stanols
Plant sterols are structurally similar to cholesterol and can be divided into sterols and stanols. Their cholesterol lowering effects have been known for some time.

Plant sterols/stanols are naturally found in a wide range of foods such as vegetable oils, nuts, seeds, whole grains, fruits and vegetables. However, for most people, it is not possible to achieve the optimum intake from ordinary foods.

Super food 5 - fruits and vegetables
All fruits and vegetables are low in saturated fat so eating more helps to keep saturated fat intake low. Fruit and vegetables are also a valuable source of cholesterol lowering soluble fibres. Try to include at least one pulse (beans, peas, lentils) everyday. Other rich sources of soluble fibre include sweet potato, aubergene, okra (ladies finger), broccoli, apples, strawberry and prunes.

Super food 6 - foods rich in unsaturated fats
Keeping our daily saturated fat intake below 20g (women) and 30g (men) is vital for cholesterol lowering, but it is equally important to replace this saturated fat with modest amounts of unsaturated fats such as those found in olive, sunflower, corn, rapeseed and other vegetable, nut and seed oils. Other foods rich in unsaturated fats include vegetable spreads, avocado, oily fish and nuts. Avoid coconut and palm oil as, unlike other these vegetable oils, they are rich in saturated fats.

6 Super Foods That Actively Help Lower Cholesterol

If you are facing difficulties in breathing, especially in the process of exhaling, you are suffering from emphysema. Emphysema is a condition in which the air sacs of the lungs are damaged and enlarged, causing breathlessness. It occurs as a result of several triggers, smoking being the most common one. Emphysema is a type of chronic obstructive pulmonary disease. People with this condition struggle to exhale, which implies that there is some obstruction in the air flow. This disease has no permanent cure but by quitting smoking, you can stop it from getting worse.

Stages
The progression and severity of emphysema occurs with the staging systems. The staging of the condition can help in developing a prognosis.

The Gold emphysema staging system
Gold is a major emphysema staging system created by a group known as the Global Initiative for Chronic Obstructive Lung Disease. The amount of air a patient can exhale forcefully in one second is determined during this stage. It is also referred to as the forced expiratory volume or FEV1.

The staging is as follows:

Stage 1: Mild emphysema (FEV1 greater than 80% of normal)
Stage 2: Moderate emphysema (FEV less than 80%, but more than 50% normal)
Stage 3: Severe emphysema (FEV lesser than 50%, but more than 30% normal)
Stage 4: Extremely severe emphysema. (FEV lesser than 30% of normal or lesser than 50% normal, with low levels of oxygen in the blood.
The BODE emphysema staging system
The condition affects several abilities. The BODE index, an acronym for BMI (body mass index), obstruction, dyspnea (breathlessness), exercise capacity (health index) is another staging system for emphysema in which the emphysema s impact on several areas of life are measured. They include the following:

Body mass index (B)
Airflow limitation or obstruction (O), which is measured by pulmonary function tests
Breathless or dyspnea (D), which is assessed thoroughly via a questionnaire
Exercise capacity (E), which is measured to check how long a person with emphysema can walk in a span of six minutes
Life expectancy
The prognosis of emphysema is impossible to be determined in any person individually. The staging system helps to identify the severity of the condition, but the future cannot be predicted. Not many studies have been undertaken for the determination of the effects of emphysema on life expectancy. The best research that has been carried out included around 100 people, which is very less. The condition varies largely among people, even if they are in the same stage.

The statistics available on emphysema are not reliable enough for individuals who wish to know their life expectancy. It is considered that if a patient falls in a higher stage, his/her long-term life expectancy is less.
