10 Pvc Doctor Tricks Experts Recommend
How a VC Can Affect Your Heart

PVCs are common and can be experienced by a wide range of people with no cause for concern. If they occur regularly, 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 nerve, or SA. Electrical signals are transmitted from there to the lower chambers of your heart or ventricles.

Causes

PVCs occur when the electrical impulse that normally starts your heartbeat in a region called the sinus node (also known as the sinoatrial or SA node) doesn't. Instead, the impulse starts in another area of your heart called the ventricles and triggers a mistimed beat. These extra beats, also called ventricular tachycardia or ventricular fibrillation, could feel as if your heart skipped a beat or is like it's fluttering. They may happen rarely and have no symptoms or they may occur frequently enough to affect your daily life. If they occur frequently or cause dizziness, weakness or fatigue, your doctor could treat them with medicine.


In most people, PVCs are harmless and don't increase your risk of developing heart disease or other health problems. Regular PVCs, however, can weaken your heart muscle over time. This is particularly relevant if the PVCs result from a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can lead to heart failure.

PVCs can trigger symptoms, such as a sensation of your heart racing a beat, or fluttering. You might also feel breathless. The fluttering may be more noticeable when you exercise or consume certain drinks or food items. People who experience chronic anxiety or stress may have more PVCs, and some medications like amiodarone digoxin, and cocaine may increase the risk of developing them.

If you have occasional PVCs your doctor may recommend lifestyle changes and medications. If you experience frequent PVCs, your physician may recommend that you avoid certain foods and drinks such as caffeine and alcohol. You can also lower your stress by taking enough rest and working out.

If you have a lot of PVCs, he may suggest a medical procedure called radiofrequency catheter ablation. This destroys the cells that are responsible for PVCs. This procedure is performed by a specialist known as an electrophysiologist. The treatment is typically successful in treating PVCs and reducing symptoms, but it does not stop them from returning in the future. In certain cases it can increase your risk of having atrial fibrillation (AFib) which can lead to stroke. This is rare, but it can be life-threatening.

Signs and symptoms

Premature ventricular contractions, also known as PVCs, may make your heart seem to flutter or skip one beat. These extra heartbeats are generally harmless, however, you should consult your physician if you have frequent episodes or symptoms like dizziness or weakness.

Normally, electrical signals start in the sinoatrial node, located in the top right-hand side of the heart. They move down to the lower chambers (or ventricles) that pump blood. The ventricles expand to force blood into the lung. They return to the heart's center to start the next cycle of pumping. However, a PVC begins in a different place, from the bundle of fibers called the Purkinje fibers in the lower left part of the heart.

When PVCs occur, they can make the heart pound or feel as if it skipped the beat. If you've experienced just a few episodes but no other symptoms, the doctor will probably not treat you. If you've got a lot of PVCs, your doctor may suggest that you undergo an electrocardiogram (ECG) to measure the heartbeat for a period of 24 hours. He or she might also suggest wearing a Holter Monitor, which records the heart's rhythm and count the number of PVCs.

People who have suffered an earlier heart attack or 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 changes. This includes cutting down on caffeine, alcohol and smoking, reducing stress and anxiety, and getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.

If you have frequent PVCs, even if you do not have other signs, you should see an expert in cardiology. These extra heartbeats can indicate an issue with the structure of your heart or other health issues and, over time, if they occur often enough, they could weaken the heart muscle. However, most people with PVCs don't have any issues. They just want to be aware that the fluttering and skippy heartbeats aren't typical.

Diagnosis

PVCs may feel like heartbeats that flutter, especially if they are frequent and intense. Patients who have a lot of them may feel they're about to faint. They can also happen with exercising, but most athletes who experience them do not have any issues with their heart or health. PVCs can be detected in tests such as an electrocardiogram (ECG) or Holter monitor. These patches contain sensors that record electrical impulses from your heart. A cardiologist can also perform an ultrasound echocardiogram to examine the heart.

A doctor may be able to determine if someone is suffering from PVCs from a history and physical examination. However, sometimes they will only notice them while examining the patient for different reasons, like after a surgery or accident. Ambulatory ECG monitoring systems can assist in detecting PVCs and other arrhythmias, and could be utilized if there's any concern of a cardiac condition.

If your cardiologist determines your heart is structurally healthy, reassurance could be all that's needed. However, if your symptoms are causing discomfort or make you feel anxious, avoiding caffeine, alcohol and over-the-counter decongestants and reducing stress may aid. Repair My Windows And Doors , maintaining a healthy weight and drinking enough fluids can all help to reduce the frequency of PVCs. If your symptoms persist or are severe, speak with your physician about possible medications that can control these symptoms.

Treatment

If PVCs are rare or don't cause symptoms, they do not usually need treatment. If you are frequently affected or frequently, your doctor may wish to look for any other heart problems and suggest lifestyle changes or medication. You may also undergo an operation (called radiofrequency cathode ablation) to get rid them.

If you suffer from PVCs in your heart, the electrical signal which creates your heartbeat is located outside of the sinoatrial (SA) node located in the upper right corner of your heart. This could cause it to feel like your heart skips a beat or is beating faster. It's not known what causes these symptoms, but they're frequent in those with other heart problems. 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 the doctor should conduct an ECG and an echocardiogram to rule out structural heart disease. They should also conduct an exercise stress test to see if the extra beats are due to physical exercise. To determine if there are other causes for the extra beats the heart catheterization or a cardiac MRI is possible.

The majority of people who suffer from PVCs are not affected and can lead an ordinary life. They may increase the risk of heart rhythm disorders that can be dangerous, especially if they occur in certain patterns. In some cases, this means that the heart muscle gets weaker and has difficulty pumping blood throughout your body.

A regular, healthy diet and a lot of exercise can reduce your chances of developing PVCs. You should avoid foods that are high in sodium and fat as well as limit caffeine and tobacco. Sleep and stress are also crucial. Certain medications can increase the risk of developing PVCs. If you're taking one of these drugs it is important to follow the doctor's advice about a healthy diet, exercise and taking your medication.

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