How a VC Can Affect Your Heart

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

The heart's rhythm is controlled by a group of fibers that are located in the upper right part of your heart. This is called the sinoatrial node, or SA. Electrical signals travel to the ventricles, or lower chambers of the heart.

Causes





PVCs are caused when the electrical impulse that normally begins your heartbeat in a part known as the sinus node (also known as the sinoatrial or SA Node) isn't. Instead, the impulse is generated in a different area of your heart, the ventricles, and causes a wrongly timed beat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. It may feel like the heart skipped a beating or feels like it is fluttering. They can happen infrequently and not cause any symptoms, but they can also happen frequently enough to affect your standard of living. Your doctor may prescribe medicine in the event that they are frequent or cause dizziness, weakness 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 especially relevant if they are triggered by a heart disease like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy, which could lead to symptoms of heart failure.

The signs of PVCs include feeling like your heart beats faster or is fluttering, and you feel exhausted. The fluttering can be more noticeable when you exercise or consume certain drinks or foods. PVCs are more prevalent in people with chronic stress or anxiety. Certain medications, such as digoxin, amiodarone, and cocaine, can also increase the risk of developing PVCs.

If you experience occasional PVCs your doctor may suggest lifestyle changes and medications. If you experience frequent PVCs, your physician may recommend avoiding 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've got a lot of PVCs, your doctor may suggest a medical procedure called radiofrequency catheter ablation, which destroys the cells that cause them. Electrophysiologists are the ones who perform this procedure. The treatment is generally effective in treating PVCs and reducing symptoms, but does not prevent them from becoming recurring in the future. In certain cases it can increase your risk of having atrial fibrillation (AFib) which can cause a stroke. This is rare, but it can be life-threatening.

Signs and symptoms

Premature ventricular contractions PVCs, also known as PVCs, can cause your heart to skip or to flutter. These extra heartbeats are harmless, but you may want to consult your doctor when they occur frequently or if you are experiencing symptoms like dizziness, or fatigue.

Normaly, electrical signals begin in the sinoatrial area, which is located in the upper right part of the heart. They then move to the lower chambers, also known as ventricles, that pump blood. The ventricles contract to propel blood into the lungs, and then return to the heart and start the next cycle of pumping. But a PVC begins in a different place that is separate from the bundle of fibers known as the Purkinje fibers, located in the lower left part of the heart.

When PVCs occur, they can make the heart beat faster or feel as if it skipped a beat. If you've experienced a few episodes and no other symptoms, the doctor will probably not treat you. But if you have a lot of PVCs and you have other symptoms, your doctor might recommend an electrocardiogram, also known as an ECG to gauge your heart rate over a 24-hour period. The doctor may also suggest wearing a Holter monitor, which will record your heartbeat over time to see how many PVCs you have.

People who have had a previous heart attack or suffer from cardiomyopathy -an illness that affects how the heart pumps blood- should be aware of their PVCs and consult a cardiologist about changes to their lifestyle. These include abstaining from alcohol, caffeine and smoking, managing stress and anxiety and ensuring adequate sleep. A cardiologist may prescribe beta blockers to slow the heartbeat.

If you have frequent PVCs even if do not have any other symptoms you should see a cardiologist. These irregular heartbeats could indicate a problem in the structure of your lungs or heart, and if they occur frequently enough, it could weaken your heart muscle. window doctor with PVCs don't experience any problems. They simply want to be aware that the fluttering and skippy heartbeats aren't typical.

Diagnosis

PVCs can feel like heartbeats that are fluttering, particularly if they're frequent and intense. People who experience them frequently might feel faint. They can also occur during exercising, but most athletes who get them do not have any issues with their health or heart. PVCs can be detected in tests like an electrocardiogram, or Holter monitor. They have sensors that record electrical impulses coming from your heart. A cardiologist could also employ an ultrasound echocardiogram to study the heart.

A doctor may be able to determine if someone is suffering from PVCs through a medical history and physical exam. Sometimes however, they might not be aware of PVCs until they examine the patient for another reason such as following an accident or a surgery. Ambulatory ECG monitoring systems can also assist in detecting PVCs and other arrhythmias, and they might be used if there's any concern of a cardiac condition.

If your cardiologist finds that your heart's structure is normal, reassurance is the only remedy required. If your symptoms are troubling or make you feel anxious, avoiding alcohol, caffeine and other decongestants as well as reducing stress levels can help. Regular exercise, maintaining a healthy weight, and drinking enough fluids can help to reduce the frequency of PVCs. If your symptoms continue or are extreme, talk to your doctor about medication options to treat them.

Treatment

If PVCs aren't causing symptoms or are not frequent, they usually don't need treatment. If you experience them frequently or frequently, your doctor may wish to check for any other heart problems and recommend lifestyle changes or medicine. You may also undergo a procedure (called radiofrequency cathode ablation) to eliminate 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 side of your heart. This could cause your heart to feel as if it skips beats or has extra beats. PVCs are more frequent among those suffering from heart disease however, it's not clear what causes them. PVCs are more likely to occur as you age, and they might occur more frequently 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. They will probably also do an exercise stress test to determine if the extra beats are due to physical exercise. To find out if there are other causes for the extra beats, a heart catheterization or a cardiac MRI could be conducted.

The majority of people with PVCs don't experience any complications and can lead a normal lifestyle. They could increase the risk of developing heart rhythm disorders that can be dangerous particularly if they develop in certain patterns. In certain cases, it means that the heart muscle becomes weaker and is having difficulty pumping blood through your body.

Regular exercise and a healthy diet can lower your risk of developing PVCs. Avoid foods high in fat and sodium, and limit your consumption of tobacco and caffeine. Also, you should try to get enough rest and reduce stress. Some medicines can also increase your risk of PVCs. If you're taking one of these medicines, it's important to follow your doctor's instructions about a healthy diet, exercise and taking your medication.

In studies of patients with PVC burdens that are excessive (more than 20% of heartbeats) there was a higher incidence of arrhythmia-induced cardiac myopathy was discovered. Certain people may require a heart transplant.
