How a VC Can Affect Your Heart

Many people experience occasional PVCs with no problems. But if windows doctor occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

A bundle of fibers in the upper right part of your heart (the sinoatrial node, also known as SA) typically regulates the heart's rhythm. Electrical signals travel to lower heart chambers or ventricles.

Causes

PVCs happen when the electrical impulse that normally begins your heartbeat in a region known as the sinus node (also known as the sinoatrial or SA node) isn't. Instead, the impulse starts in a different area of your heart, the ventricles, and causes an untimed beat. These extra beats are also known as ventricular tachycardia, and ventricular fibrillation. It could feel as if the heart beats faster or feels like it is fluttering. They can occur rarely without causing any symptoms, but they could be frequent enough to impact your quality of life. Your doctor may prescribe medication if they are frequent or cause dizziness, weakness or fatigue.

In most people, PVCs are harmless and aren't likely to increase your risk of developing heart disease or other health issues. Over time, frequent PVCs can weaken the heart muscle. This is especially relevant if the PVCs are triggered by a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can lead to heart failure.

PVCs can cause symptoms like a feeling of your heart racing an beat, or fluttering. It is also possible to feel breathless. The fluttering may be more apparent when you exercise or consume certain drinks or food items. People who experience chronic stress or anxiety can have more PVCs and certain medications like amiodarone digoxin, and cocaine may increase the chance of developing them.

If you experience occasional PVCs your doctor may recommend lifestyle changes and medications. If they're a frequent occurrence, you may have to avoid certain drinks and foods, such as caffeine and alcohol. You can also reduce your stress levels, and make sure you get enough sleep and exercise.

If you have a lot of PVCs Your doctor might recommend a medical procedure referred to as radiofrequency catheter ablation. This procedure destroys the cells that cause them. The procedure is carried out by a specialist, known as an electrophysiologist. The treatment is generally successful in treating PVCs and reducing symptoms, but does not prevent them from becoming recurring in the future. In certain cases, it can increase your risk of having atrial fibrillation (AFib) which could lead to a stroke. It is not common, but it can be life-threatening.

Signs and symptoms

Premature ventricular contracts, or PVCs can cause your heart to skip or to flutter. These extra heartbeats can be harmless, but you may be advised to consult your physician when they occur frequently or if you notice symptoms like dizziness or fatigue.

Normally, electrical signals start at the sinoatrial junction, which is in the top right portion of the heart, and travel down to the lower chambers (or ventricles) that pump blood. The ventricles expand to push the blood into the lungs. They then return to the center to start the next cycle of pumping. However, a PVC starts in a different location and is located in the bundle of fibers known as the Purkinje fibers in the bottom left portion of the heart.

When PVCs occur, they can make the heart beat or feel like it skipped a beat. If you experience just a few episodes but no other symptoms, your doctor will probably not treat you. But if you have a large number of PVCs, the doctor may recommend an electrocardiogram, or ECG to determine your heart rate over the course of 24 hours. The doctor may also recommend wearing a Holter monitor that will track your heartbeat over time to determine how many PVCs you have.

People who have suffered a previous heart attack or cardiomyopathy - an illness that affects the method by which the heart pumps blood - should take their PVCs very seriously and consult a cardiologist about lifestyle changes. These include the avoidance of alcohol, caffeine, and smoking, managing anxiety and stress and ensuring adequate sleep. A cardiologist might also prescribe medication to slow the heartbeat like a beta blocker.

If you are experiencing frequent PVCs even if you don't have any other signs, you should see an expert in cardiology. These extra heartbeats can indicate problems with the structure of your heart or other health conditions, and over time, if they occur often enough, they may weaken the heart muscle. However, most people with PVCs don't experience any problems. They would like to know if irregular heartbeats or fluttering is normal.

Diagnosis

PVCs can be felt as fluttering or skipped heartbeats, particularly when they're frequent or intense. People who experience them often might feel faint. Exercise can trigger them, but most athletes who experience them have no heart or health problems. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses from your heart. A cardiologist can also perform an ultrasound echocardiogram to study the heart.

Most of the time, a doctor will be able to tell whether the patient has PVCs from a history and physical exam. Sometimes, however, they may only be able to detect PVCs when they examine a patient for another reason, such as after an accident or surgical procedure. Ambulatory ECG monitoring systems also aid in detecting PVCs and other arrhythmias and they might be used if there's any concern of a cardiac condition.





If your cardiologist determines that your heart is structurally normal, reassurance is the only remedy required. If your symptoms are causing you discomfort or make you feel anxious, staying away from alcohol, caffeine, and over the counter decongestants, and the reduction of stress could aid. Regular exercise and maintaining a healthy weight, and drinking enough fluids can all aid in reducing the frequency of PVCs. If the symptoms persist or are severe, talk with your physician about possible medication options to treat the symptoms.

Treatment

If PVCs are rare or don't cause symptoms, they do not usually require treatment. If you have them often or frequently, your doctor may wish to examine for other heart issues and recommend lifestyle changes or medications. You could also undergo an operation (called radiofrequency cathode ablation) to eliminate of them.

If you suffer from PVCs in your heart the electrical signal that creates your heartbeat is located outside of the sinoatrial (SA) node that is located in the upper right corner of your heart. This could cause your heart to feel like it skips beats or has additional beats. PVCs are more frequent among those with heart problems, but it's not known the reason behind them. PVCs may increase in frequency as you age, and may be more frequent during exercise.

A physician should perform an ECG along with an echocardiogram for a patient who has frequent and painful PVCs to determine if there are structural heart problems. The doctor may also conduct an exercise stress test to determine if the increased heartbeats are caused by physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study could be performed to find other reasons for the increased beats.

The majority of people with PVCs do not experience any issues and can live an ordinary life. But they can increase your risk of having dangerous heart rhythm problems particularly if you have certain patterns of them. In some cases this means that the heart muscle becomes weaker and is unable to pump blood throughout your body.

Regular exercise and a balanced diet will lower the risk of developing PVCs. You should avoid foods that are high in fat and sodium as well as reduce your intake of caffeine and tobacco. You should also try to get enough sleep and reduce stress. Certain medicines can also increase the risk of developing PVCs. If you're taking one of these drugs it is important to follow the doctor's advice about eating well, exercising and taking your medication.

In studies of patients with PVC burdens that are excessive (more than 20% of total heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was discovered. This can lead to the need for a transplant in some patients.
