How a VC Can Affect Your Heart

PVCs are common and can be experienced by a wide range of people without causing any problems. If they happen frequently, PVCs may weaken your heart and increase the risk for heart failure.

The rhythm of your heart is usually controlled by a group of fibers located in the upper right part of your heart. This is known as the sinoatrial nerve, or SA. Electrical signals are transmitted to the ventricles, or lower chambers of the heart.

Causes

PVCs are caused when the electrical impulse that typically starts your heartbeat at a point known as the sinus node (also called the sinoatrial or SA node) does not. Instead, the impulse is generated in a different area of your heart–the ventricles–and causes an untimed beat. These extra beats, also known as ventricular tachycardia, or ventricular fibrillation, can feel like your heart skipped a beat, or it feels like it is fluttering. They may happen rarely and have no symptoms or they can occur frequently enough to affect your daily life. Your doctor might prescribe medication in the event that they are frequent or cause dizziness, weakness or fatigue.

PVCs are generally harmless and don’t increase your risk of heart disease. Frequent PVCs, however, can weaken your heart muscle over time. This is particularly relevant if the PVCs are caused by an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that could lead to heart failure.

PVCs can cause symptoms, such as a sensation of your heart beating a beat, or fluttering. You may also feel exhausted. The fluttering could be more noticeable if you exercise, or eat or drink certain beverages or foods. People who experience chronic anxiety or stress may have more PVCs and certain medications like amiodarone digoxin, and cocaine can increase the likelihood of developing them.

If you are experiencing occasional PVCs Your doctor might suggest lifestyle changes and medication. If they are a frequent occurrence, you may have to stay clear of certain foods and beverages like caffeine and alcohol. You can also take steps to reduce your stress and take advantage of plenty of rest and exercise.

If you’ve got a lot of PVCs Your doctor might suggest a medical procedure known as radiofrequency catheter ablation. It eliminates the cells that are responsible for them. This procedure is performed by a specialist called an electrophysiologist. It is typically effective in treating PVCs and reducing symptoms however it does not stop them from recurring in the future. In certain instances, it can increase the risk of having atrial fibrillation (AFib), a condition that can result in stroke. It is not common however it could be life-threatening.

Symptoms

Premature ventricular contractions or PVCs, can cause your heart seem to skip or flutter the beat. These heartbeats that are not normal can be harmless, but you may be advised to consult your physician in the event of frequent heartbeats or if you experience symptoms like dizziness, or fatigue.

The electrical signals typically begin in the sinoatrial node which is in the top right side of the heart, and move down to the lower chambers (or ventricles) that pump blood. Then, the ventricles expand to push blood into your lungs, and then return to your heart to begin the next pumping cycle. But a PVC starts in a different place that is separate from the bundle of fibers known as the Purkinje fibers, in the lower left part of the heart.

When PVCs occur, they can make the heart beat faster or feel as if it skipped the beat. If you have only a few episodes, but no other symptoms, your doctor will probably not treat you. If you have many PVCs the doctor may suggest you undergo an electrocardiogram (ECG) to determine the heartbeat for a period of 24 hours. The doctor may also suggest wearing a Holter Monitor that records your heartbeat and tracks the number of PVCs.

People who have had a prior heart attack or have cardiomyopathy -which affects the way that the heart pumps blood -and must be aware of their PVCs and speak with an expert in cardiology about lifestyle changes. windows doctor includes abstaining from alcohol, caffeine and smoking, reducing anxiety and stress and getting enough rest. A cardiologist can prescribe beta blockers to slow the heartbeat.

Even if you don’t experience any other signs however, you should have PVCs checked by an cardiologist if they occur often. These extra heartbeats can point to a problem with the structure of your heart or other health conditions and, over time, when they are frequent enough, they may weaken the heart muscle. Most people who suffer from PVCs do not have any issues. They are interested in knowing if the rapid heartbeats, or the skipping of heartbeats is normal.

Diagnosis

PVCs can feel like heartbeats that are fluttering, particularly if they’re frequent and intense. People who experience them often may feel faint. They can also occur with exercising, but most athletes who experience them don’t have any problems with their heart or health. PVCs can show up on tests such as an electrocardiogram or a Holter monitor. These patches contain sensors which record electrical impulses that come from your heart. A cardiologist may also use an ultrasound echocardiogram for examining the heart.

A doctor will usually be able to determine if a patient has PVCs by examining them and taking their medical history. Sometimes, however, they may not be aware of PVCs until they examine patients for a different reason such as following an accident or a surgery. Ambulatory ECG monitoring systems also help detect PVCs and other arrhythmias, and could be utilized if there’s any concern of heart disease.

If your cardiologist has determined that your heart is structurally healthy, reassurance could be all that’s needed. If your symptoms are causing you discomfort or make you feel anxious, staying away from alcohol, caffeine and over-the prescription decongestants, as well as decreasing stress can help. Regular exercise, maintaining a healthy weight and drinking enough fluids can aid in reducing the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, speak to your doctor about medications that could be able to manage them.

Treatment

If PVCs don’t cause symptoms or are not frequent they aren’t usually in need of treatment. If they are frequent your doctor may need to examine for heart problems or suggest lifestyle modifications. You might also get an operation to rid yourself of them (called radiofrequency catheter ablation).

If you have PVCs in your heart the electrical signal that causes your heartbeat begins somewhere other than at the sinoatrial (SA) node that is located in the upper right-hand corner of your heart. This could cause it to feel like your heart skips beats or is beating faster. It’s not known what causes these, but they’re more common in people who have other heart conditions. PVCs may increase in frequency as we age and can occur more often during exercising.

If a patient has frequent and painful PVCs, a physician should conduct an ECG and an echocardiogram to determine if there is a structural heart problem. The doctor may also conduct an exercise stress test to determine if the increased heartbeats are related to physical activity. A heart catheterization, cardiac MRI or nuclear perfusion study can be conducted to determine other reasons for the increased beats.

The majority of people with PVCs do not suffer from any issues and can live an ordinary life. However, they may increase your risk of having dangerous heart rhythm issues especially if you are suffering from certain patterns of them. In some instances, this means that the heart muscle becomes weaker and is unable to pump blood throughout your body.

Regular exercise and a healthy diet can lower the chances of developing PVCs. Avoid foods high in fat and sodium and limit your intake of tobacco and caffeine. You should also try to get enough rest and reduce stress. Some medicines can also increase the risk of developing PVCs. So if you take one of these medications it is important to follow your doctor’s instructions about eating well, exercising and taking your medication.

Studies of patients with a high amount of PVCs (that’s more than 20 percent of their total heart beats) found that they had a higher risk of arrhythmia-induced cardiomyopathy. This can lead to the need for a transplant in certain people.
