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.

5 natural ways to control your blood pressure

Blood pressure rises with each heartbeat and falls as your heart relaxes. The normal blood pressure should be less than 120/80 mm hg. An increase or decrease on either end can cause various problems.

Here are some of the natural ways to control your blood pressure.

1. Having a diet low in sodium

In the event of a high blood pressure, curtail the consumption of foods that are rich in sodium. However, research reveals that sometimes it is not just enough to cut down on sodium in your diet. A person suffering from high bp should consume foods rich in minerals like calcium, magnesium and potassium as well to keep his/her bp in check.

2. Drink plenty of water and curtail the consumption of alcohol

In case a person suffers from low blood pressure, it is advisable to drink plenty of water as low blood pressure is usually accompanied by bouts of dehydration, and consumption of water can help increase your blood pressure. Also, health drinks, which are rich in electrolytes, help your raise blood pressure. But one should avoid drinks that are high in sugar, and abating your alcohol consumption also helps to quite an extent.

3. Burn extra calories and exercise regularly

Blood pressure usually increases with weight. Being overweight can lead to sleep apnea, which is marked by disruptive breathing while you sleep, which in turn condition can lead to increased blood pressure. Studies have found that weight loss is one of the most effective ways to control high bp. Regular physical activity is also advised to maintain a stable blood pressure.

4. Avoid long, hot showers

The hot water in showers and spas can expand your blood vessels, which can often lead to a drop in blood pressure. A common sign of this would be dizziness and fainting while taking a bath. Therefore, for people suffering from this condition, using warm water rather than hot water is advisable.

5. Completely avoid stress

One of the contributing factors of high blood pressure is chronic stress. Stress tends to affect blood pressure in indirect ways. Many react to stress by overeating, consumption of alcohol and smoking, all of which can increase your blood pressure. Try to know what triggers your stress and take steps to avoid it.

Coronary artery disease or CAD is the name given to the heart condition in which the major blood vessels that supply your heart with blood, oxygen and nutrients, also called coronary arteries, get blocked, damaged or diseased.

Blockages usually happen when cholesterol-containing deposits called plaque deposit in your arteries. Plaque narrows the lumen of your coronary artery which means your heart gets lesser and lesser oxygen and nutrients to function properly.
Inflammation is also to blame for coronary artery disease.
Common symptoms of CAD include

Angina or pain in the chest
Shortness of breath
If the blockage is complete, you can get a heart attack.
Common Diagnostic tests
When you go to a heart specialist, she will ask questions about your medical history and follow it up with a physical exam and order routine blood and diagnostic tests to confirm CAD like:

Electrocardiogram (ECG): An ECG records electrical signals as they travel through your heart revealing evidence of a previous heart attack or one that s happening. Holter monitoring is a type of ECG where you wear a portable monitor for 24 hours as you go about your normal daily activities. Abnormalities in the results suggest reduced blood flow to the heart signaling CAD.
Echocardiogram: This test uses sound waves to produce images of your heart. It helps your doctor determine whether all parts of your heart wall are contributing to your heart's pumping activity. If certain parts are moving weakly it can mean damage to muscle due to a heart attack or because of receiving too little oxygen- again signaling CAD.
Exercise Stress test: This test is done by making you do exercises like walking on a treadmill or riding a stationary bike during an ECG. Sometimes, medication to stimulate your heart may be used instead of exercise.
This again detects areas in your heart that receive less blood flow.

Cardiac catheterization or angiogram. A special dye is injected into your coronary arteries to observe blood flow through your heart in a test known as an angiogram.
The dye is sometimes also injected into the arteries through a long, thin, flexible tube called catheter that is threaded through an artery in your leg to the arteries in your heart. This procedure is called cardiac catheterization. This test is very good in diagnosing CAD as the dye outlines narrow spots and blockages on the X-ray images of your heart.
Heart scans. Computerized tomography or CT can help your doctor actually see calcium deposits in your arteries that can be narrowing your arteries. If a substantial amount of calcium deposits are found, coronary artery disease could be the reason.
MRI scans are also done to diagnose CAD.

Arrhythmia is a disorder which is characterized by improper and irregular heartbeats; be it too slow or too fast. This problem occurs when the electrical impulses that are used to regulate your heartbeat don t work in the correct manner. Your heart may beat irregularly, too slow or too fast.

Symptoms
Although this disorder does not yield many symptoms, a few noticeable symptoms of arrhythmia are slow heartbeat, or a racing heartbeat, chest pain, breathing difficulties and dizziness. Arrhythmia can lead to inefficient pumping by the heart, leading to bouts of fainting. A severe symptom of this disorder is ventricular fibrillation, wherein the ventricles tend to quiver instead of transporting blood. This symptom can cut off blood supply to the vital organs, which may lead to death.

Causes

Coronary artery disease: In this disease, arteries of the heart can get blocked, leading to irregular heart beat and impaired heart functioning.
A heart attack: An ongoing heart attack usually leads to irregular heartbeats.
High blood pressure: High blood pressure problems make you more vulnerable to this condition.
Impaired functioning of the thyroid glands: An overactive or underactive thyroid gland can lead to heart arrhythmia.
Excessive smoking and alcohol consumption: These habits can cause problems with the blood vessels in the body, thus increasing risks of this particular condition as well as other cardio-vascular diseases.
Stress: Too much stress can lead to high blood pressure; that is again linked to heart arrhythmia.
Treatment
Mild symptoms of arrhythmia do not require treatment. However, complications resulting from it warrant treatment. The various treatment options for this condition are:

Pacemaker: A pacemaker is a device that is used to regulate your heart rhythms. It is placed in the body by a surgical procedure and an insulated wire is put, connecting the heart to the pacemaker. In case of an irregular heartbeat, the pacemaker sends out impulses to correct the improper heartbeat.
Implantable cardioverter-defibrillator: This device is used to prevent a dangerous symptom of heart arrhythmia, a symptom wherein the ventricle quivers. It is similar to a pacemaker as it is also placed near the collarbone. In case it detects an abnormal rhythm, it sends out shocks to reset the heart rhythm.
Maze procedure: This is a surgical procedure wherein incisions are made on the upper heart tissue to create a scar tissue. Scar tissues act as insulators to prevent stray impulses.
Alternative therapies: Alternative procedures such as yoga and meditation can help remedy the disorder.
