How a VC Can Affect Your Heart

PVCs are common and can be experienced by a variety of people without causing any problems. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

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

Causes

PVCs occur by the electrical impulse that normally initiates your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) is not initiated. The impulse actually starts in the ventricles, causing an irregular heartbeat. These extra beats, called ventricular tachycardia or fibrillation, can feel like your heart skipped a beat, or it feels like it is fluttering. They may occur infrequently without causing any symptoms, but they may also happen frequently enough to affect your standard of living. If they are very frequent or cause weakness, dizziness, or fatigue, your doctor may treat them with medicine.

PVCs are generally harmless and don't increase your risk of heart disease. Over time, repeated PVCs can weaken the heart muscle. This is particularly relevant if the PVCs are caused by a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which could lead to heart failure.

The signs of PVCs include feeling like your heart beats faster or is fluttering, and you feel exhausted. The fluttering could be more noticeable when you exercise or consume certain foods or beverages. PVCs are more prevalent in those suffering from chronic stress or anxiety. Some drugs, like digoxin, amiodarone and cocaine, can increase the risk.

If you are experiencing occasional PVCs Your doctor may suggest lifestyle changes and medications. If you experience frequent PVCs, your doctor might suggest that you stay away from certain drinks and foods, such as caffeine and alcohol. You can also lower your stress levels by getting enough sleep and working out.

If you have many PVCs, he may suggest a medical procedure called radiofrequency catheter ablation, which eliminates the cells that cause PVCs. Electrophysiologists are the ones who perform this procedure. It is generally effective in treating PVCs and reducing symptoms however it does not stop them from recurring in the future. In some cases it may increase your risk of having atrial fibrillation (AFib) which can result in stroke. It is not common however it could be life-threatening.

Symptoms

Premature ventricular contractions, also known as PVCs, can cause your heart appear to flutter or skip the beat. These extra heartbeats are harmless, but you may want to consult your doctor in the event of frequent heartbeats or if you are experiencing symptoms like dizziness, or fatigue.

Normaly, electrical signals begin in the sinoatrial region, which is in the upper right-hand corner of the heart. They then move to the lower chambers, or ventricles, where blood pumps are located. Then, the ventricles contract to propel the blood into your lungs and return to the heart and start the next cycle of pumping. A PVC begins in a different location, the Purkinje fibres bundle in the bottom left of the heart.

When PVCs occur, the heart may feel like it is skipping a beat or pounding. If you experience only one or two episodes, and no other symptoms are present, your cardiologist will probably not treat you. If you've got a number of PVCs the doctor may recommend an electrocardiogram, or ECG to gauge your heart rate over 24 hours. The doctor may also suggest wearing a Holter Monitor which tracks your heartbeat and tracks the number of PVCs.

People who have suffered previously from a heart attack or cardiomyopathy, an illness that affects the way the heart pumps blood - should take their PVCs very seriously and speak to a cardiologist regarding lifestyle changes. Those include the avoidance of alcohol, caffeine, and smoking, managing anxiety and stress, and ensuring adequate sleep. A cardiologist may prescribe medications to slow the heartbeat for example, a beta blocker.

If you have frequent PVCs even if don't have any other signs, you should see an expert in cardiology. These heartbeats that are irregular can point to a problem with the structure of your heart or other health conditions and, over time when they are frequent enough, they could weaken the heart muscle. Most people with PVCs don't experience any problems. They want to know if the irregular heartbeats or fluttering is normal.

Diagnosis

PVCs can feel like heartbeats that are fluttering, particularly if they're frequent and intense. Patients who have a lot of them may feel they're about to faint. They can also occur during training, even though many athletes who get them do not have any issues in their heart or health. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram, which makes use of ultrasound to study the heart and see how it's functioning.

Often, a doctor will be able to determine if a person has PVCs through a medical history and physical examination. Sometimes however, they might only be able to detect PVCs when they examine the patient for another reason, such as after an accident or a surgery. Ambulatory ECG monitoring systems also aid in detecting PVCs and other arrhythmias, and could be utilized if there's any concern of a cardiac condition.

If your cardiologist has determined that your heart is structurally healthy, reassurance could be all that's needed. If your symptoms are troubling or cause you to feel anxious, avoiding alcohol, caffeine and over-the prescription decongestants, as well as the reduction of stress could aid. Regular exercise, maintaining a healthy weight, and drinking enough fluids can help to reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, speak to your doctor about medications that may be able to control these symptoms.

Treatment

If PVCs do not cause any symptoms or occur rarely generally, they don't require treatment. If you experience them frequently and frequently, your doctor might want to check for any other heart problems and suggest lifestyle changes or medications. You may also undergo a procedure (called radiofrequency cathode ablation) to eliminate of them.

If you suffer from PVCs, the electrical signal that causes your heartbeat is generated from a place outside of the sinoatrial node (SA node) in the top right corner of your heart. This can cause your heart to feel as if it skips beats or has extra beats. They're more common among people suffering from heart disease however, it's not clear the reason behind them. PVCs can increase in frequency as we age and can occur more often during exercising.





If a patient has frequent and painful PVCs the doctor should perform an ECG and an echocardiogram to rule out structural heart disease. The doctor will also likely perform an exercise stress test in order to determine if the increased heartbeats are due to physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion studies can be performed to find other reasons for the extra beats.

Most people with PVCs do not experience any complications and can lead a normal lifestyle. But they can increase the risk of developing dangerous heart rhythm problems particularly if you have certain patterns of them. In some instances, this means the heart muscle gets weaker and has trouble pumping blood through your body.

A healthy and balanced diet and plenty of exercise can help reduce your risk of developing PVCs. Avoid foods that are high in fat and sodium as well as reduce your intake of caffeine and tobacco. Sleep and stress are equally important. window doctor can also increase the risk of developing PVCs. So if you take one of these drugs it's crucial to follow the doctor's advice about eating well, exercising and taking your medication.

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