How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by a wide range of people without causing any problems. If they occur regularly, PVCs can weaken your heart muscle and increase your risk of heart failure.

The rhythm of your heart is controlled by a bundle of fibers located in the upper right-hand corner of your heart. This is known as the sinoatrial node or SA. Electrical signals are transmitted to the ventricles or lower chambers of your heart.

Causes

PVCs happen when the electrical impulse that typically starts your heartbeat in a part known as the sinus node (also called the sinoatrial node or SA node) isn't. Instead, the impulse is generated in a different area of your heart called the ventricles and triggers an untimed beat. These extra beats, called ventricular tachycardia or ventricular fibrillation, can feel like your heart skipped a beat or feels like it is fluttering. They may happen rarely and not cause any symptoms, or they can happen often enough to impact your quality of life. Your doctor may prescribe medication in the event that they are frequent or cause dizziness, weakness or fatigue.

For the majority of people, PVCs are harmless and don't increase your risk of heart disease or other health issues. Over time, repeated PVCs can weaken the heart muscle. This is especially true if they are caused by a heart condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy, which may lead to symptomatic heart failure.

PVCs can trigger symptoms, such as a sensation of your heart beating a beat, or fluttering. You may also feel exhausted. The fluttering could be more apparent when you exercise, or eat or drink certain drinks or foods. PVCs are more common in those suffering from chronic anxiety or stress. Certain medications, such as digoxin, amiodarone, and cocaine, can increase the risk.

If you experience occasional PVCs your doctor might suggest lifestyle changes and medication. If you experience frequent PVCs, your doctor might suggest that you stay away from certain drinks and foods, such as alcohol and caffeine. You can also reduce stress by having enough sleep and working out.

If you've got a lot of PVCs, your doctor may suggest a medical procedure known as radiofrequency catheter ablation. This procedure destroys the cells that cause them. This is done by a specialist called an electrophysiologist. It is generally successful in treating the PVCs and reducing symptoms, but it doesn't stop them from recurring in the future. In some cases it can increase the risk of atrial fibrillation (AFib), which can cause stroke. It's not common, but it can be life-threatening.

Signs and symptoms

Premature ventricular contractures or PVCs may cause your heart to skip or flutter. These heartbeats can be harmless, however, you should consult your physician if you have frequent episodes or symptoms like dizziness or weakness.

The electrical signals typically begin in the sinoatrial node located in the top right portion of the heart. They travel down to the lower chambers (or ventricles) that pump blood. Then, the ventricles contract to propel the blood into your lungs and then return to your heart to start the next cycle of pumping. A pvc Doctor starts at a different spot that is the Purkinje fibres bundle in the bottom left of the heart.

When PVCs happen, the heart may appear to be racing or pounding. If you only have a few episodes, and there are no other symptoms your cardiologist may not treat you. But if you have a lot of PVCs the doctor may recommend an electrocardiogram, or ECG, window & door Doctor to measure the heart's rate over 24 hours. The doctor may also suggest wearing a Holter monitor, which will record your heart rhythm over time, allowing you to see how many PVCs you have.

Anyone who has suffered previously from a heart attack or have suffered from 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 modifications. This includes cutting down on caffeine, alcohol and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist might prescribe medications to slow heartbeat, for example, beta blockers.

Even if you don't experience any other symptoms however, you should have PVCs examined by a cardiologist if they happen frequently. These heartbeats that are irregular could signal a problem with the structure of your lungs or heart, and if they happen often enough, it could weaken the heart muscle. The majority of people with PVCs do not experience any issues. They would like to know if rapid heartbeats, or the skipping of heartbeats is normal.

Diagnosis

PVCs may be felt as fluttering or skipped heartbeats, especially if they are frequent or intense. People who experience them regularly may feel weak. Exercise can trigger them, but most athletes who suffer from them do not have heart or health issues. PVCs may show up on tests such as an electrocardiogram, or Holter monitor. They have sensors that record electrical impulses from your heart. A cardiologist could also employ an echocardiogram, which makes use of ultrasound to look at the heart and observe how it's working.

Often, a doctor will be able to identify if someone has PVCs from a history and physical examination. However, sometimes they will not be aware of them until they examine the patient for other reasons, such as after a surgery or accident. Ambulatory ECG monitoring systems also help detect PVCs and other arrhythmias and can be used when there is a concern of cardiac disease.

If your cardiologist concludes that your heart is structurally healthy, reassurance could be all that's needed. However, if your symptoms are bothersome or make you feel anxious, avoiding alcohol, caffeine and other decongestants as well as reducing stress levels can aid. Regular exercise and maintaining a healthy weight, and drinking enough fluids can help to reduce the frequency of PVCs. If your symptoms persist or are severe, speak with your physician about possible medication options to treat these symptoms.

Treatment

If PVCs aren't common or don't cause symptoms, they do not usually need treatment. If they occur frequently, your doctor might be able to look for heart issues or suggest lifestyle adjustments. You may also undergo a procedure to get rid of them (called radiofrequency catheter ablation).

If you have PVCs the electrical signal that triggers your heartbeat begins somewhere other than the sinoatrial node (SA node) located in the upper right part of your heart. It can feel like your heart skips a beat or has extra beats. It's not known what causes them, but they're more common in people who have other heart conditions. PVCs are more frequent with age and might happen more often during exercises.

If a patient is experiencing frequent and painful PVCs the doctor is required to perform an ECG and an echocardiogram to rule out heart disease that is structural. They may also perform an exercise stress test to determine if the extra beats are due to physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study could be conducted to determine other reasons for the additional beats.

The majority of people who suffer from PVCs don't experience any issues and can live a normal lifestyle. However, they may increase the risk of developing dangerous heart rhythm issues especially if you are suffering from certain patterns of them. In some cases, that means the heart muscle gets weaker and is unable to pump blood through your body.

Regular exercise and a balanced diet will lower the chances of developing PVCs. Avoid foods that are high in fat and sodium and limit caffeine and tobacco. Also, you should try to sleep enough and reduce stress. Certain medications can increase your risk for PVCs. If you are taking one of these medicines, it's important to follow your doctor's instructions regarding eating healthy, exercising and taking your medication.

Studies of patients suffering from an excessive amount of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher risk of arrhythmia-induced cardiomyopathy. This can result in the need for a transplant in certain patients.
