How a VC Can Affect Your Heart

Many people experience occasional PVCs without any problems. If they are frequent, PVCs may weaken your heart and increase your chance of suffering from heart failure.

The rhythm of your heart is usually controlled by a bundle of nerve fibers situated in the upper right part of your heart. This is called the sinoatrial node or SA. Electrical signals are transmitted from there to the lower heart chambers, or ventricles.

Causes

PVCs happen by the electrical impulse that normally initiates your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) is not initiated. Instead, the impulse is generated in a different part of your heart--the ventricles--and causes an untimed beat. These extra beats, called ventricular tachycardia or fibrillation, may feel like your heart skipped a beat, or it feels like it is fluttering. They can happen infrequently and have no symptoms or they may occur frequently enough to impact your daily life. Your doctor may prescribe medicine when they occur frequently or cause weakness, dizziness or fatigue.

PVCs are generally harmless and do not increase the risk of heart disease. In time, repeated PVCs can weaken the heart muscle. This is especially true if the PVCs are triggered by conditions like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can lead to heart failure.

PVCs can cause symptoms such as a feeling of your heart beating an beat, or basement window Repair fluttering. You may also feel exhausted. The fluttering may be more evident when you exercise or eat or drink certain foods or beverages. PVCs are more common in people with chronic stress or anxiety. Certain medications, such as digoxin, amiodarone and cocaine, can increase the risk of developing PVCs.

If you are experiencing occasional PVCs Your doctor might recommend lifestyle changes and medicines. If they're a frequent occurrence, you may need to stay clear of certain foods and beverages like caffeine and alcohol. You can also take steps to reduce your stress and make sure you get enough sleep and exercise.

If you have many PVCs, your doctor may suggest a medical procedure called radiofrequency catheter ablation. It eliminates the cells that are responsible for them. Electrophysiologists are the ones who perform this procedure. It is typically successful in treating the PVCs and reducing symptoms however it does not stop them from occurring in the future. In some cases it may increase your risk of having atrial fibrillation (AFib) which could lead to stroke. It is not common but it could be life-threatening.

Symptoms

Premature ventricular contractions, also known as PVCs, may make your heart appear to skip or flutter one beat. These heartbeats can be harmless, however, you should consult your physician when you experience frequent episodes or signs like dizziness or weakness.

Normaly, electrical signals begin in the sinoatrial, located in the upper right corner of the heart. They then travel to the lower chambers, or ventricles, where blood pumps are located. The ventricles then contract to push the blood into the lung. They return to the heart's center to begin the next cycle of pumping. However, a PVC begins in a different location and is located in the bundle of fibers, known as the Purkinje fibers in the left-hand side of the heart.

When PVCs happen they can make the heart feel as if it's skipping a beat or pounding. If you experience just a few episodes but no other symptoms, the cardiologist probably won't treat you. But if you have a lot of PVCs and you have other symptoms, your doctor might suggest an electrocardiogram, or ECG to determine your heartbeat over the course of 24 hours. The doctor may also recommend wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs.

People who have suffered previously from a heart attack or replace broken window glass cardiomyopathy, an illness that affects the heart's blood flow - must take their PVCs seriously and consult a cardiologist regarding lifestyle modifications. This includes abstaining from caffeine, alcohol, and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe medications to slow the heartbeat like beta blockers.

Even if you don't have any other signs however, you should have PVCs examined by an expert in cardiology if they occur often. These irregular heartbeats could indicate problems with the structure of your heart or other health issues and, over time, when they happen frequently enough, they may weaken the heart muscle. But most people with PVCs don't have any issues. They simply want to know that the fluttering or racing heartbeats aren't normal.

Diagnosis

PVCs may feel like heartbeats that flutter, particularly if they're frequent and intense. People who experience them often may feel faint. Exercise can trigger them, but many athletes who suffer from them have no heart or health problems. PVCs could show up in tests such as an electrocardiogram (ECG) or Holter monitor. These patches contain sensors that record electrical impulses coming from your heart. A cardiologist could also employ an ultrasound echocardiogram to study the heart.

A doctor may be able to identify if a person has PVCs from a history and physical exam. Sometimes however, they might only be able to detect PVCs when they examine a patient for another reason, like following an accident or a surgery. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They can be used to detect heart disease in the event of any concern.

If your cardiologist has determined that your heart is structurally healthy, reassurance might be all that's needed. If your symptoms are troubling, or cause you to be anxious, avoiding alcohol, caffeine and over-the drug decongestants and reducing stress may aid. Getting regular exercise, staying at a healthy weight and drinking enough water can also reduce your episodes of PVCs. If your symptoms persist or severe, talk to your doctor about medication that could help control them.

Treatment

If PVCs are rare or do not cause symptoms, they rarely require treatment. If you experience them frequently or frequently, your doctor may wish to examine for any other heart problems and recommend lifestyle changes or medications. You might also get a procedure to get rid of them (called radiofrequency catheter ablation).

If you have PVCs in your heart the electrical signal that creates your heartbeat is located other than at the sinoatrial (SA) node that is located in the upper right-hand corner of your heart. This can cause your heart to feel as if it skips a beating or has additional beats. PVCs are more prevalent among people with heart problems, but it's not known what causes them. PVCs can increase in frequency with age and might happen more frequently during exercises.

A physician should perform an ECG along with an echocardiogram for a patient who suffers from frequent and painful PVCs to identify structural heart conditions. They should also conduct an exercise stress test to see whether the extra beats are due to physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion study could be done to look for other causes for the extra beats.

The majority of people with PVCs do not suffer from any problems and can enjoy a normal lifestyle. They could increase the risk of dangerous heart rhythm disorders, especially if they occur in certain patterns. In some instances, this means that the heart muscle becomes weaker and is having difficulty pumping blood through your body.

A regular, healthy diet and plenty of exercise can reduce your risk of developing PVCs. You should avoid foods that are high in sodium and fat and restrict your intake of tobacco and caffeine. Sleep and stress are equally crucial. Certain medicines can also increase your risk of PVCs. If you're taking one of these drugs it's crucial to follow the doctor's advice regarding eating healthy, exercising and taking your medication.

In studies of patients suffering from PVC burdens that are excessive (more than 20% of heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was found. Certain people may require a heart transplant.
