How a VC Can Affect Your Heart

Many people have occasional PVCs without any problems. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

A bundle of fibers in the top right portion of your heart (the sinoatrial, or SA, node) usually controls your heart rhythm. Electrical signals travel from there to the lower chambers of your heart, or ventricles.

Causes

PVCs occur when the electrical impulse that typically begins your heartbeat in a region known as the sinus node (also called the sinoatrial or SA node) does not. Instead, the impulse starts in a different part of your heart, the ventricles, and causes a wrongly timed beat. These extra beats, also called ventricular tachycardia or ventricular fibrillation, may feel like your heart skipped a beat or feels like it is fluttering. They can happen infrequently, causing no symptoms, but they can also happen frequently enough to affect your quality of life. If they are very frequent or cause weakness, dizziness, or fatigue, your door doctor near me might treat them with medication.

For most people, PVCs are harmless and don't increase your risk of 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 conditions like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can lead to heart failure.

PVCs can cause symptoms like a feeling of your heart skipping one beat, or even fluttering. You may also feel breathless. The fluttering may be more noticeable if you exercise, or eat or drink certain beverages or foods. People who suffer from chronic stress or anxiety can have more PVCs, and some medications such as amiodarone, digoxin, and cocaine can increase the likelihood of developing them.

If you have occasional PVCs your doctor might suggest lifestyle changes and medications. If you experience frequent PVCs, your physician may recommend avoiding certain drinks and foods, like caffeine and alcohol. You can also lower your stress by having enough sleep and working out.

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. This is done by a specialist called an electrophysiologist. It is usually successful in treating the PVCs and reducing symptoms, however, it doesn't prevent them from occurring in the future. In some cases it may increase your risk of having atrial fibrillation (AFib) which could result in a stroke. This is rare however it could be life-threatening.

Symptoms

Premature ventricular contractions, or PVCs, may make your heart appear to skip or flutter the beat. These extra heartbeats can be harmless, however you might need to see your doctor in the event of frequent heartbeats or if you notice symptoms such as dizziness or fatigue.

The electrical signals typically begin in the sinoatrial node located in the top right-hand side of the heart, and move down to the lower chambers (or ventricles) that pump blood. Then, the ventricles contract to propel the blood into your lungs and return to the heart to begin the next pumping cycle. A pvc doctor starts at a different spot in the Purkinje fibres bundle at the left side of the heart.

When PVCs occur, they cause the heart pound or feel as if it skipped the beat. If you have only a few episodes, and there are no other symptoms, your cardiologist will probably not treat you. But if you have a number of PVCs the doctor may recommend an electrocardiogram, or ECG to gauge your heartbeat over 24 hours. He or she may also recommend wearing a Holter monitor that records the heart's rhythm over time to see the number of PVCs you have.

If you've suffered a heart attack in the past or have cardiomyopathy -an illness that affects how the heart pumps blood -and should take their PVCs seriously and talk to an expert in cardiology about lifestyle changes. This includes the avoidance of alcohol, caffeine, and smoking, managing anxiety and stress and getting enough sleep. A cardiologist can prescribe medications to slow heartbeat, like a beta blocker.

If you have frequent PVCs, even if you don't have any other signs, you should see an expert in cardiology. These irregular heartbeats could be a sign of a problem with the structure of your heart or to other health conditions, and over time, when they happen frequently enough, they may weaken the heart muscle. The majority of people with PVCs do not have any issues. They want to know if the irregular heartbeats or fluttering is normal.

Diagnosis

PVCs may feel like heartbeats that are fluttering particularly if they're frequent and intense. People who experience them frequently may feel faint. They can also occur with exercise, though many athletes who experience them don't have any problems with their health or heart. PVCs may show up in tests such as an electrocardiogram (ECG) or Holter monitor. These are sticky patches that have sensors to record electrical signals from your heart. A cardiologist may also use an ultrasound echocardiogram for examining the heart.

A doctor is often able to tell whether a patient has PVCs by looking at them and taking a medical history. But sometimes they might not be aware of them until they examine the patient for other reasons, for instance after an accident or surgery. Ambulatory ECG monitors are able to detect PVCs as well as other arrhythmias. They are able to detect heart disease in the event of any reason to be concerned.

If your cardiologist concludes that your heart's structure is normal, reassurance will be the only remedy required. If your symptoms are troubling or make you feel anxious, staying away from alcohol, caffeine, and other decongestants and reducing stress may aid. Regular exercise, maintaining a healthy weight, and drinking enough fluids can aid in reducing the frequency of PVCs. If your symptoms persist or severe, talk to your doctor about medications that could be able to control the symptoms.

Treatment

If PVCs don't cause symptoms or happen rarely, they usually don't need treatment. If you experience them frequently or frequently, your window & door doctor may wish to examine for other heart issues and recommend lifestyle changes or medication. You could also have a procedure (called radiofrequency cathode ablation) to get rid of them.

If you have PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere other than at the sinoatrial (SA) node, which is located in the upper right-hand corner of your heart. It can feel like your heart skips a beat or has extra beats. PVCs are more prevalent among people suffering from heart disease however, it's not clear what causes them. PVCs can increase in frequency as we age and can occur more often during exercising.

If a patient is experiencing frequent and painful PVCs, a physician should perform an ECG and an echocardiogram to determine if there is a structural heart problem. The glazing doctor will also likely conduct an exercise stress test to determine if the extra heartbeats are due to physical activity. To determine whether there are other reasons for the extra beats, a heart catheterization or an MRI can be performed.

The majority of people with PVCs are not affected and live an ordinary life. They can increase the risk of dangerous heart rhythm disorders particularly if they develop in certain patterns. In some cases, that means that your heart muscle gets weaker and is unable to pump blood throughout your body.

Regular exercise and a healthy diet can reduce your chances of developing PVCs. Avoid foods high in fat and sodium and limit your intake of tobacco and caffeine. Stress and sleep are also important. Certain medications can increase the risk of getting PVCs. So if you take one of these drugs, it's important to follow the doctor's advice about a healthy diet, exercise and taking your medication.

Studies of patients suffering from a high burden of PVCs (that's more than 20% of their total heart beats) found that they had a higher incidence of arrhythmia-induced cardiomyopathy. This could lead to the need for a transplant in a few individuals.
