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.

the window doctor of fibers in the top right portion of your heart (the sinoatrial, or SA, node) typically regulates the heart's rhythm. Electrical signals travel to the ventricles or lower chambers of your heart.

Causes

PVCs happen when the electrical impulse that normally initiates your heartbeat in a region called the sinus node (also known as the sinoatrial or SA node) doesn't. Instead, the impulse begins in another area of your heart, the ventricles, and causes a wrongly timed beat. These extra beats, also called ventricular tachycardia or ventricular fibrillation, can feel like your heart skipped a beat or feels like it's fluttering. They can occur infrequently and not cause any symptoms, or they can occur frequently enough to interfere with your daily life. If they happen frequently or cause dizziness, weakness, or fatigue, your doctor may treat them with medication.

For most people, PVCs are harmless and don't increase your risk of developing heart disease or other health problems. In time, frequent PVCs can weaken the heart muscle. This is particularly when the PVCs result from conditions like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can cause heart failure.

The symptoms of PVCs include a feeling that your heart beats faster or is fluttering, and you feel breathless. The fluttering may be more apparent if you exercise, or eat or drink certain foods or beverages. People with chronic anxiety or stress may have more PVCs, and some medications like amiodarone digoxin, and cocaine may increase the chance of developing them.

If you are experiencing occasional PVCs your doctor might suggest lifestyle changes and medications. If they are a frequent occurrence, you may have to avoid certain drinks and foods like caffeine and alcohol. You can also lessen stress by taking enough rest and working out.

If double glazing doctor got a lot of PVCs Your doctor may suggest a medical procedure known as radiofrequency catheter ablation, which eliminates the cells responsible for them. Electrophysiologists are the ones who execute this procedure. It is usually successful in treating the PVCs and reducing symptoms, however, it doesn't prevent them from occurring in the future. In some instances it may increase the risk of developing atrial fibrillation (AFib), which can result in a stroke. This isn't common but it could be life-threatening.

Symptoms

Premature ventricular contractions or PVCs, can cause your heart appear to flutter or skip a beat. These extra heartbeats can be harmless, but you may be advised to consult your physician in the event of frequent heartbeats or if you experience symptoms like dizziness, or fatigue.

Normaly, electrical signals begin in the sinoatrial, located in the upper right part of the heart. They then travel to the lower chambers, also known as ventricles, where blood pumps are located. The ventricles contract to propel blood into the lungs, and return to the heart and start the next pumping cycle. A PVC begins in a different place in the Purkinje fibers are located in the left-hand side of the heart.

When PVCs occur, they make the heart beat faster or feel like it skipped the beat. If you experience a few episodes and no other symptoms, your doctor probably won't be able to treat you. If you have a lot of PVCs, your doctor may suggest that you undergo an electrocardiogram (ECG) to measure the heartbeat over the course of 24 hours. He or she may also recommend wearing a Holter monitor that will track your heart rhythm over time to see how many PVCs you have.

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

If you are experiencing frequent PVCs even if you do not have other signs, you should see a cardiologist. These heartbeats that are irregular could signal a problem with the structure of your heart or lungs and if they happen often enough, it could weaken the heart muscle. However, most people suffering from PVCs don't experience any problems. They just want to be aware that the fluttering or skippy heartbeats aren't typical.

Diagnosis

PVCs may feel like heartbeats that are fluttering, especially if they are frequent and intense. People who experience them frequently may feel weak. Exercise can cause them, but many athletes who suffer from these symptoms do not have heart or health issues. PVCs can be detected in tests such as an electrocardiogram (ECG) or Holter monitor. These patches have sensors which record electrical impulses that come from your heart. A cardiologist could also employ an echocardiogram, which uses ultrasound to examine the heart and observe how it's functioning.

A doctor may be able to identify if someone is suffering from PVCs from a patient's history and physical exam. Sometimes it is possible that they not be aware of PVCs until they examine the patient for another reason such as following an accident or surgical procedure. Ambulatory ECG monitors can detect PVCs, as well as other arrhythmias. They may be used to detect heart disease in the event of any concern.

If your cardiologist determines your heart is structurally healthy, reassurance could be all that's needed. If your symptoms are causing you discomfort or cause you to be anxious, avoiding alcohol, caffeine and over-the prescription decongestants, as well as reducing stress may aid. Getting regular exercise, staying at a healthy weight and drinking enough fluids can help reduce the frequency of PVCs. If your symptoms are persistent or severe, talk to your doctor about medication that may be able to manage them.

Treatment

If PVCs are rare or don't cause symptoms, they don't usually require treatment. If they happen frequently your doctor may want to check for heart issues or suggest lifestyle adjustments. You may also undergo a procedure to get rid of them (called radiofrequency catheter ablation).

If you have PVCs in your heart, the electrical signal which creates your heartbeat is located other than at the sinoatrial (SA) node located in the upper right-hand corner of your heart. This can make it feel like your heart skips beats or is beating faster. It's not clear what causes them, but they're more common in people with other heart problems. PVCs may increase in frequency as you age, and they may be more frequent during exercising.

If a patient is experiencing frequent and painful PVCs doctors is required to perform an ECG and an echocardiogram to determine if there is a structural heart problem. The doctor will also likely conduct an exercise stress test to determine if the additional heartbeats are related to physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion study can be performed to find other causes for the increased beats.

The majority of people who suffer from PVCs do not suffer from any issues and can live an ordinary life. They may increase the risk of developing dangerous heart rhythm disorders particularly if they develop in certain patterns. In some cases, this means that the heart muscle becomes weaker and has difficulty pumping blood throughout your body.

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

In studies of patients suffering from high PVC burdens (more than 20% of the total heartbeats), a higher rate arrhythmia-induced cardiac myopathy was discovered. Some patients may require an organ transplant.
