How a VC Can Affect Your Heart

A lot of people experience occasional PVCs and have no issues. If they occur often, PVCs may weaken your heart and increase your risk for heart failure.

The rhythm of your heart is usually controlled by a group of fibers that are located in the upper right part of your heart. This is known as the sinoatrial nerve, or SA. Electrical signals are transmitted to the ventricles, or lower chambers of the heart.

Causes

PVCs occur when the electrical impulse that normally initiates your heartbeat in a region called the sinus node (also known as the sinoatrial or SA Node) does not. Instead, the impulse is generated in another area of your heart--the ventricles--and causes an untimed beat. These extra beats are known as ventricular tachycardia, and ventricular fibrillation. It could feel as if the heart beats faster or feels like it is fluttering. They can happen infrequently and not cause any symptoms, but they can occur frequently enough to affect your standard of living. If window doctor are very frequent or cause dizziness, weakness, or fatigue, your doctor could treat them with medicine.

PVCs are generally harmless and don't increase your risk of developing heart disease. In time, repeated PVCs can weaken the heart muscle. This is especially the case if they are caused by a heart-related condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which could lead to symptoms of heart failure.

The signs of PVCs include feeling like your heart skips a beat or flutters, and you may feel breathless. The fluttering could be more evident when you exercise or consume certain foods or drinks. PVCs are more common for those who suffer from chronic stress or anxiety. Some medications, like digoxin, amiodarone, and cocaine, can increase the risk.

If you experience occasional PVCs, your doctor may suggest lifestyle changes and medications. If you are prone to frequent PVCs, your doctor might suggest that you stay away from certain foods and drinks, such as alcohol and caffeine. You can also reduce stress by taking enough rest and working out.

If you have a lot of PVCs, your doctor may suggest a medical procedure known as radiofrequency catheter ablation, which eliminates the cells that are responsible for them. This is done 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 some cases it can increase the risk of atrial fibrillation (AFib) which is an illness that can cause stroke. It is not common, but it could be life-threatening.

Symptoms

Premature ventricular contractions or PVCs may cause your heart to skip or be fluttering. These heartbeats can be harmless, but you should consult your physician if you have frequent episodes or other symptoms such as dizziness or weakness.

Normaly, electrical signals begin in the sinoatrial, located in the upper right-hand corner of the heart. They then move to the lower chambers, also known as ventricles, that pump blood. The ventricles expand to pump blood into the lung. They return to the heart's center to begin the next cycle of pumping. However, a PVC starts in a different location, 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 a few episodes and no other symptoms, your cardiologist probably won't treat you. If you've got a large number of PVCs, the doctor may recommend an electrocardiogram, or ECG to determine the heart's rate over the course of 24 hours. The doctor may also recommend wearing a Holter monitor that will track your heartbeat over time to see the number of PVCs you have.

If you've had a previous heart attack or suffer from cardiomyopathy -- a condition that affects the way that the heart pumps blood- must be aware of their PVCs and talk to an expert in cardiology about lifestyle changes. This includes cutting down on caffeine, alcohol and smoking, managing anxiety and stress, and getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.

If you experience frequent PVCs, even if you don't have any other signs, you should see an expert in cardiology. These extra heartbeats may be a sign of a problem with the structure of your lungs or heart, and if they occur often enough, they can weaken your heart muscle. Most people with PVCs don't experience any issues. They just want to know that the fluttering or skipping heartbeats aren't normal.

Diagnosis

PVCs may be felt as fluttering or skipped heartbeats, particularly when they are frequent or intense. People who experience them regularly may feel weak. They can also happen with exercising, but most athletes who suffer from them don't have issues with their heart or health. window doctor can be detected on tests such as an electrocardiogram or a Holter monitor. They use sticky patches with sensors on them to record electrical impulses from your heart. A cardiologist could also employ an echocardiogram that uses ultrasound to examine the heart and observe how it's working.

Often, a doctor will be able to identify if a person is suffering from PVCs through a medical history and physical examination. Sometimes, they may not be aware of them until they examine the patient for other reasons, for instance following an accident or surgery. Ambulatory ECG monitoring systems also aid in detecting PVCs and other arrhythmias, and they might be used when there is a concern of a cardiac condition.

If your cardiologist determines that your heart is structurally normal, reassurance is the only treatment needed. If your symptoms are bothersome or make you feel anxious, avoiding alcohol, caffeine, and over the prescription decongestants, as well as the reduction of stress could help. Regular exercise, being at a healthy weight, and drinking enough water can reduce your episodes of PVCs. If your symptoms are persistent or extreme, consult your physician about the medications that could be able to manage the symptoms.





Treatment

If PVCs aren't causing symptoms or happen rarely, they usually don't need treatment. If they occur frequently your doctor may want to check for heart issues or suggest lifestyle adjustments. You could also undergo an operation (called radiofrequency cathode ablation) to eliminate of them.

If you suffer from PVCs in your heart the electrical signal that creates your heartbeat is located outside of the sinoatrial (SA) node, which is 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 unclear what causes these symptoms, but they're common in people who have other heart issues. PVCs may increase in frequency as you age, and may be more frequent during exercise.

If a patient experiences frequent and painful PVCs the doctor should conduct an ECG and an echocardiogram to rule out structural heart disease. The doctor may also perform an exercise stress test in order to determine if the extra heartbeats are due to physical activity. To determine whether there are any other causes for the extra beatings an invasive heart catheterization or a cardiac MRI is possible.

Most people with PVCs don't experience any complications and can lead an ordinary life. They can increase the risk of developing dangerous heart rhythm disorders particularly if they happen in certain patterns. In some cases this means that the heart muscle gets weaker and has difficulty pumping blood throughout your body.

Regular exercise and a healthy diet can lower your risk of developing PVCs. Avoid foods that are high in sodium and fat as well as restrict your intake of tobacco and caffeine. Also, you should try to sleep enough and manage stress. Certain medications can increase your risk of getting PVCs. So if you take one of these medicines, it's important to follow your doctor's recommendations regarding eating healthy, exercising and taking your medication.

In studies of patients suffering from PVC burdens that are excessive (more than 20% of heartbeats), a higher rate arrhythmia-induced myopathy in the heart was observed. This can result in a need for a heart transplant in a few people.
