How a VC Can Affect Your Heart
PVCs are common and may be experienced by a variety of people without causing any issues. But if they occur frequently, PVCs can weaken your heart muscle and increase your risk of heart failure.
The rhythm of your heart is controlled by a bundle of fibers that are located in the upper right-hand corner of your heart. This is called the sinoatrial nerve, or SA. Electrical signals are transmitted to the ventricles, or lower chambers of the heart.
Causes
PVCs are caused when the electrical impulse that normally triggers your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) does not. The impulse actually starts in the ventricles, which causes an untimed heartbeat. These extra beats, also called ventricular tachycardia or fibrillation, can feel like your heart skipped a beat or feels like it is fluttering. They can occur rarely and not cause any symptoms, but they may also happen frequently enough to affect your standard of living. If they are very frequent or cause weakness, dizziness, or fatigue, your doctor could treat them with medication.
In most people, PVCs are harmless and do not increase the risk of heart disease or other health problems. A lot of PVCs, however, can weaken the heart muscle over time. This is especially the case if they are caused by a heart disease like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy, which may lead to symptomatic heart failure.
PVCs can cause symptoms, such as a sensation of your heart beating one beat, or even the feeling of your heart fluttering. It is also possible to feel breathless. The fluttering may be more noticeable when you exercise or consume certain drinks or foods. PVCs are more prevalent in people with chronic anxiety or stress. Some medications, such as digoxin, amiodarone and cocaine, may increase the risk.
If you have occasional PVCs, your doctor may suggest lifestyle changes and medication. If you have frequent PVCs, your doctor might recommend that you avoid certain drinks and foods, like caffeine and alcohol. You can also reduce stress by taking enough rest and working out.
If you have many PVCs Your doctor might recommend a medical procedure referred to as radiofrequency catheter ablation. This procedure destroys the cells that cause them. Electrophysiologists are the ones who carry out this procedure. It is typically effective in treating PVCs and reducing symptoms, however, it doesn't prevent them from occurring in the future. In certain cases it can increase the risk of developing atrial fibrillation (AFib), which can lead to a stroke. This isn't common but it could be life-threatening.
Symptoms
Premature ventricular contractions, or PVCs, can make your heart seem to skip or flutter one beat. These heartbeats that are not normal can be harmless, but you may want to consult your doctor when they occur frequently or if you experience symptoms like dizziness, or fatigue.
Normaly, electrical signals begin in the sinoatrial, located in the upper right-hand corner of the heart. Repair My Windows And Doors travel to the lower chambers, also known as ventricles, that pump blood. The ventricles then contract to push the blood into the lung. They return to the heart's center to start the next cycle of pumping. A PVC starts at a different spot that is the Purkinje fibers are located in the left side of the heart.
When PVCs occur they can make the heart feel like it is skipping a beat or pounding. If you experience only one or two episodes, and no other symptoms are present the cardiologist will likely not treat you. If you have many PVCs and your doctor might recommend that you undergo an electrocardiogram (ECG) to measure the heartbeat for 24 hours. The doctor may also recommend wearing a Holter monitor that records your heartbeat over time to determine the number of PVCs you have.
People who have had a prior heart attack or suffer from cardiomyopathy -an illness that affects the way that the heart pumps blood -- should be aware of their PVCs and speak with a cardiologist about lifestyle changes. This includes cutting down on caffeine, alcohol and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist may prescribe beta blockers to slow down the heartbeat.
If you experience frequent PVCs even if don't have any other symptoms, you should consult a cardiologist. These irregular heartbeats could indicate a problem in the structure of your heart or lungs, and if they occur often enough, it could weaken the heart muscle. The majority of people with PVCs don't experience any issues. They simply want to know that the fluttering or skippy heartbeats aren't typical.
Diagnosis
PVCs may feel like heartbeats that are fluttering particularly if they're frequent and intense. People who experience them regularly may feel faint. Exercise can trigger them, but most athletes who suffer from them have no heart or health problems. PVCs can be detected in tests such as an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses from your heart. A cardiologist might also use an echocardiogram, which uses ultrasound to study the heart and observe how it's working.
A doctor may be able to identify if someone is suffering from PVCs from a history and physical examination. However, sometimes they will only notice them while examining the patient for other reasons, for instance following an accident or 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 heart disease.
If your cardiologist concludes that your heart is structurally normal, reassurance will be the only treatment needed. However, if your symptoms are bothersome or make you feel anxious, staying away from caffeine, alcohol and over-the-counter decongestants and reducing stress can aid. Regular exercise, being at a healthy weight and drinking enough fluids can reduce your episodes of PVCs. If your symptoms persist or extreme, consult your doctor about medications that could be able to manage the symptoms.
Treatment
If PVCs aren't causing symptoms or happen rarely they aren't usually in need of treatment. If they happen frequently your doctor may want to check for heart problems or suggest lifestyle modifications. You could also have an operation (called radiofrequency cathode ablation) to eliminate of them.
If you have PVCs in your heart the electrical signal that creates your heartbeat is located different than the sinoatrial (SA) node located in the upper right corner of your heart. This can make it feel like your heart skips beats or has a few extra beats. PVCs are more frequent among those suffering from heart disease however, it's not clear what causes them. PVCs are more frequent with age and might happen more often during exercise.
A doctor should conduct an ECG as well as an echocardiogram on a patient that suffers from frequent and painful PVCs to rule out structural heart diseases. The doctor may also conduct an exercise stress test to determine if the additional heartbeats are due to physical activity. To determine whether there are any other causes for the extra beatings an invasive heart catheterization or cardiac MRI could be conducted.
The majority of people with PVCs do not suffer from any problems and can enjoy an ordinary life. But they can increase your risk of having dangerous heart rhythm problems especially if you are suffering from certain patterns of them. In certain cases, it means the heart muscle gets weaker and is unable to pump blood through your body.
Regular exercise and a balanced diet can reduce your risk of developing PVCs. Avoid foods that are high in sodium and fat, and limit your intake of caffeine and tobacco. Stress and sleep are also crucial. Certain medicines can also increase the risk of developing PVCs. If you're taking one of these medications it's crucial to follow the doctor's advice about a healthy diet, exercise 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 cardiac myopathy was found. This can lead to the need for a transplant in certain individuals.
