How a VC Can Affect Your Heart

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

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

Causes

PVCs happen by the electrical impulse that normally triggers your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) is not initiated. The impulse actually begins in the ventricles, causing a mistimed heartbeat. These extra beats are also known as ventricular tachycardia and ventricular fibrillation. It may feel like the heart skipped a beating or feels like it is fluttering. They may happen rarely and cause no symptoms, or they may occur frequently enough to interfere with your daily life. Your doctor may prescribe medicine in the event that they are frequent or cause weakness, dizziness or fatigue.

For most people, PVCs are harmless and do not increase the risk of developing heart disease or other health issues. In time, repeated PVCs can weaken the heart muscle. This is particularly when the PVCs are triggered by an illness like dilated Cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can cause heart failure.

PVCs can cause symptoms such as a feeling of your heart racing an beat, or fluttering. You might also feel breathless. The fluttering could be more noticeable when you exercise or have certain foods or drinks. PVCs are more prevalent in those suffering from chronic anxiety or stress. Some medications, like digoxin, amiodarone, and cocaine, can also increase the risk.

If you have occasional PVCs your doctor might suggest lifestyle changes and medication. If they are a frequent occurrence, you may have to stay clear of certain drinks and foods, such as alcohol and caffeine. You can also reduce your stress and make sure you get enough sleep and exercise.

If you have lots of PVCs the doctor might suggest a medical treatment called radiofrequency catheter ablation. It destroys the cells that are responsible for PVCs. the window doctor are the ones who carry out this procedure. The treatment is generally effective in treating PVCs, reducing symptoms but does not prevent them from recurring in the future. In some cases, it can increase your risk of atrial fibrillation (AFib) which can lead to stroke. This is rare but it could be life-threatening.

Signs and symptoms

Premature ventricular contractions or PVCs, can cause your heart appear to flutter or skip a beat. These extra heartbeats are harmless, however you might want to consult your doctor in the event of frequent heartbeats or if you notice symptoms like dizziness or fatigue.

Normally, electrical signals begin in the sinoatrial node which is in the top right side of the heart, and descend to the lower chambers (or ventricles) which pump blood. The ventricles contract to propel blood into your lungs and return to the heart and start the next cycle of pumping. But a PVC starts at a different spot, 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 or feel as if it skipped one beat. If you only have a few episodes, and there are no other symptoms your cardiologist may not be able to treat you. If you've got a lot of PVCs, your doctor may recommend that you undergo an electrocardiogram (ECG) to monitor your heartbeat for 24 hours. He or she might also suggest wearing a Holter Monitor which tracks your heartbeat and tracks the number of PVCs.

People who have had a previous heart attack or suffer from cardiomyopathy -an illness that alters the way the heart pumps blood - should be aware of their PVCs and consult a cardiologist about changes to their lifestyle. These include cutting down on caffeine, alcohol and smoking, managing stress and anxiety, and getting enough rest. A cardiologist might also prescribe medication to slow heartbeat, such as beta blockers.

Even if there aren't any other signs, you should still get PVCs checked by an expert in cardiology if they occur frequently. These irregular heartbeats could be a sign of an issue with the structure of your heart or other health conditions and, over time, when they are frequent enough, they may weaken the heart muscle. But most people suffering from PVCs do not experience any issues. They simply want to be aware that the fluttering and skippy heartbeats aren't typical.

Diagnosis

PVCs can be akin to heartbeats that are fluttering particularly if they're frequent and intense. People who get lots of them might feel like they're about to faint. Exercise can trigger them, but many athletes who experience them do not have heart or health problems. PVCs can be detected in tests like an electrocardiogram, or Holter monitor. These patches have sensors that record electrical impulses coming from your heart. A cardiologist might also use an echocardiogram that uses ultrasound to examine the heart and determine how it's working.

A doctor may be able to identify if a person is suffering from PVCs through a medical history and physical exam. But sometimes they might not be aware of them until they examine the patient for different reasons, like after a surgery or accident. Ambulatory ECG monitors are able to detect PVCs, as well as other arrhythmias. They can be used to detect cardiac disease if there is any reason to be concerned.

If your cardiologist determines that your heart's structure is normal, reassurance is the only treatment needed. However, if your symptoms are bothersome or cause you to feel anxious, avoiding caffeine, alcohol and over-the-counter decongestants and reducing stress may aid. Regular exercise, maintaining a healthy weight, and drinking enough fluids can all help to reduce the frequency of PVCs. If your symptoms continue or are severe, talk to your doctor about treatments that could help control them.





Treatment

If PVCs aren't causing symptoms or are not frequent generally, they don't require treatment. If they occur frequently your doctor may need to examine for heart problems or suggest lifestyle changes. You could also undergo an operation (called radiofrequency cathode ablation) to get rid them.

When you have PVCs the electrical signal that causes your heartbeat begins somewhere different than the sinoatrial nerve (SA node) located in the upper right corner of your heart. This could cause it to feel like your heart skips beats or has a few extra beats. PVCs are more frequent among those with heart problems, but it's not known what causes them. PVCs are more likely to occur as you age, and they might occur more frequently during exercises.

If a patient experiences frequent and painful PVCs, a physician should perform an ECG and an echocardiogram to rule out heart disease that is structural. The doctor will also likely conduct an exercise stress test in order to determine if the extra heartbeats are caused by physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study can be conducted to determine other causes for the additional beats.

The majority of people who suffer from PVCs don't experience any problems and can enjoy a normal lifestyle. They can increase the risk of developing dangerous heart rhythm disorders particularly if they develop in certain patterns. In some instances, this means that your heart muscle gets weaker and is having difficulty pumping blood through your body.

A healthy, regular diet and regular exercise can reduce the chances of developing PVCs. You should avoid foods that are high in fat and sodium, and you should also reduce your intake of caffeine and tobacco. Also, you should try to get enough sleep and reduce stress. Certain medicines can also increase the risk of developing PVCs. If you are taking any of these medications it is essential to follow your doctor's advice regarding healthy eating exercising, as well as taking your medication.

In studies of patients with high PVC burdens (more than 20% of heartbeats) there was a higher incidence of arrhythmia-induced myopathy in the heart was observed. This could lead to the need for a transplant in some people.
