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 Happens When the Electrical Activity of Your Heart Changes?

The lungs take in oxygen and leave out carbon dioxide through breathing. It often does not get noticed but is the most vital function. When a person is not able to breathe properly, then the overall physical ability of a person is reduced. Even walking a few steps or doing simple chores can seem daunting tasks. Therefore, shortness of breath can be very limiting and may alter the quality of life of the patient.

The medical term being dyspnea, it can be short or long-term, acute or chronic. Any problem in the heart or lungs can cause shortness of breath.

Shortness of breath can be caused by various conditions including:

Asthma
Lung infections
Heart conditions including congestion and failure
Allergies
Fever
Any systemic illness or infection
Chronic obstructive pulmonary disease
Pneumonia
Bronchitis
Given that shortness of breath is caused by almost any ill health condition, especially in people with chronic conditions, it is best that the lungs are empowered to improve their function and do not cause shortness of breath. The idea is to delay the onset of shortness of breath and also to reduce the severity.

Some techniques to reduce shortness of breath are:

Breathe by reducing the rate of respiration. This reduces shallow breathing, which often happens, and so improves the amount of oxygen that reaches the system with each breath.
The patient should learn to relax, sit, and pace around without exertion.
Become aware of air movement during respiration   controlled breathing and active cycle of breathing techniques.
Postural drainage   Depending on the area of the lung that is causing shortness of breath, the person is made to lie prone and turn to a side that will allow the fluid in that region to drain out.
Overall relaxation techniques to improve airflow and control short of breath.
Avoid bending down, as it can induce shortness of breath.
Over-eating at one go in one meal should be avoided.
Weight needs to be maintained, especially if not under control. This can lead to shortness of breath without any associated medical condition either.
The patient should learn to push objects instead of pulling them.
Heavy objects should not be lifted but moved down at ground level.
Avoid extreme hot or cold showers.
Quit smoking as it causes various lung problems.
Help physiotherapy provides for people who are short of breath:

Improve exercise tolerance
Calms the person
Allows the person to control symptoms
Improve the quality of life
Provide manual treatment

Can Physiotherapy Cure Shortness Of Breath?

Our survival is solely reliant on the working of the heart. It is this that makes the prospect of a heart failure so fatal and so terrifying. Notwithstanding what the heart evokes, a heart failure is not indicative of a defunct heart; but only a situation when the heart pumps weaker than what is generally deemed as natural. Consequently, the blood flows at a slower rate to the heart and the body that in turn increases pressure in the heart. The oxygen that is produced by the heart in such a scenario is scanty and insufficient for the body. 

body responds with its own defense mechanism, as the heart, in an attempt to hold more blood, stretches its chambers. Though this strenuous effort may keep the blood moving, it would gradually and inevitably weary the heart with all the effort. Subsequently, the kidney responds by retaining more salt and fluid in the body. These fluids may accumulate in different parts of the body, mainly in the legs, feet, ankles leading to congestion in the body. This very condition in medical terminology is referred to as congestive heart failure. 

Different causes can contribute to the onset of such a fatal condition. Some of them are

Coronary artery disease: In such a condition, the arteries supply insufficient amount of oxygen and blood to the heart. Subsequently, the heart receives scanty amount of nutrients and oxygen.
Heart attack: The sudden, unanticipated blockage of the coronary artery and the ensuing stoppage of the flow of the blood lead to a heart attack. The heart muscles are damaged in such a case and prevent the proper functioning.
Diseases: Though the term may be generic and over expansive, most of the ailments which people suffer from tend to manifest themselves by posing a potential threat to the functioning of the heart. A high blood pressure, kidney disease, even a thyroid disease can cause congestive heart failure.
Every disorder is preceded by certain symptoms, and congestive heart failure is no different. Some of them are

Fatigue: This is one of the most perceptible symptoms of congestive heart failure. One of the earliest premonitions of an impending heart failure is a nagging sense of weariness and lethargy.
Swelling: As the condition is characterized by accumulation and build-up of fluids in various part of the body, swelling is an inevitable symptom of this condition and a clear indication of the ailment.

Congestive Heart Failure - Factors that Make it Fatal

The news of Sridevi's sudden and unexpected demise was a shock for the entire nation and left a number of questions in the minds of the people. However, there are multiple reasons which are under speculation and can be attributed to her death - cardiac arrest, heart attack and death due to accidental drowning. Usually, cardiac arrest and heart attack are two things which most people use interchangeably, however, there is a big difference between the two. 

Difference between cardiac arrest and heart attack: 
A cardiac arrest is far deadlier considering that it comes without a warning or any prior indication of a problem. Here, the heart just stops beating and immediate first-aid can make a lot of difference between life and death. Electrical shock is the best way to revive a patient and should be given within a few minutes of such an arrest. 

On the other hand, a person suffers a heart attack when there is a blockage in the artery which prevents the smooth flow of oxygen-rich blood from reaching the heart. It is important to note that unlike a cardiac arrest the signs of heart attack start slow and persists for long. 

A heart attack is one of the common causes of cardiac arrest, but not always it is the case. A cardiac arrest happens most commonly when the heart is receiving more than 300 impulses per minute or due to absent electrical impulses. In the first instance an electrical shock is a lifesaving technique and in the second, the patient can be treated with certain medications and a temporary pacemaker. 

Symptoms of cardiac arrest:
The symptoms of cardiac arrest are immediate and extreme.

A fainting spell or a sudden collapse
Loss of consciousness
No pulse or breathing 
Symptoms of a heart attack 

Discomfort along with chest pain 
Shortness of breath
Nausea with vomiting
Sweating
Headache and jawpain
Prevention of a cardiac arrest:
What makes this a deadly condition is that you cannot tell your risks of having one and therefore the next best thing to do is to lower your risks. 
The best way to do that is to:

Follow a diet that is balanced and nutritious
Alcohol should be consumed in moderation 
Quit smoking
Stay physically active
How can you prevent a heart attack?

Keep yourself fit and exercise regularly
Keep your cholesterol level under check 
Limit your alcohol intake 
If you are obese, control your weight
Intake a heart-friendly diet.
Now that the distinction is clear between the two, it is recommended that everyone should get themselves screened for potential heart problems on a regular basis. In case of a query or concern consult an expert and get your answers. 

Cardiac Arrest And Heart Attack - Understanding The Difference Between The Two!

Cholesterol is a type of fatty acid that is produced by the liver. The body uses cholesterol to perform various activities such as synthesizing of hormones, bile acid and vitamin D. Ayurveda views it as an important component of the body in terms of lubrication.
