How a VC Can Affect Your Heart A lot of people experience occasional PVCs and have no issues. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure. The rhythm of your heart is controlled by a group of nerve fibers situated in the upper right part of your heart. This is known as the sinoatrial node, or SA. Electrical signals travel from this node to the lower chambers of your heart, or ventricles. Causes PVCs happen when the electrical impulse that normally starts your heartbeat at a point called the sinus node (also known as the sinoatrial node or SA node) does not. The impulse actually begins in the ventricles, which causes a mistimed heartbeat. These extra beats are also known as ventricular tachycardia and ventricular fibrillation. They may feel like the heart skipped a beat or feels like it is fluttering. They can occur rarely without causing any symptoms, but they can also happen frequently enough to affect your quality of living. If they occur frequently or cause dizziness, weakness, or fatigue, your doctor may treat them with medicine. In most people, PVCs are harmless and do not increase the risk of heart disease or other health issues. In time, repeated PVCs can weaken the heart muscle. This is particularly relevant if the PVCs are triggered by an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can lead to heart failure. The signs of PVCs include feeling like your heart beats slower or it flutters. repairmywindowsanddoors may feel exhausted. The fluttering may be more apparent when you exercise, or eat or drink certain drinks or foods. PVCs are more common in people with chronic anxiety or stress. Some medications, like digoxin, amiodarone or cocaine, can increase the risk. If you experience occasional PVCs Your doctor may suggest lifestyle changes and medication. If they are a regular occurrence, you may need to avoid some foods and beverages like caffeine and alcohol. You can also take steps to lessen your stress levels, and make sure you get enough sleep and exercise. If you've got a lot of PVCs Your doctor might suggest a medical procedure known as radiofrequency catheter ablation. This procedure destroys the cells that cause them. The procedure is carried out by a specialist known as an electrophysiologist. It is typically successful in treating the PVCs and reducing symptoms, however it does not stop them from occurring in the future. In certain cases, it may increase the risk of atrial fibrillation (AFib) which is a condition that can result in stroke. This is rare, but it can be life-threatening. Symptoms Premature ventricular contractures or PVCs may cause your heart to skip or be fluttering. These extra heartbeats are usually harmless, however, you should consult your physician in case you experience frequent episodes or symptoms like dizziness or weakness. The electrical signals typically begin in the sinoatrial node, which is in the top right portion of the heart, and descend to the lower chambers (or ventricles) that pump blood. Then, the ventricles contract to propel the blood into your lungs and then return to your heart and start the next cycle of pumping. A PVC begins in a different place in the Purkinje fibres bundle in the left-hand side of the heart. When PVCs occur, they can make the heart beat faster or feel as if it skipped the beat. If you experience only a few episodes, and no other symptoms are present the cardiologist will likely not prescribe treatment. If you have many PVCs the doctor may recommend that you undergo an electrocardiogram (ECG) to determine the heartbeat for 24 hours. The doctor might also recommend wearing a Holter monitor, which will record your heart rhythm over time, allowing you to see how many PVCs you have. People who have suffered a previous heart attack or have suffered from cardiomyopathy – an illness that affects the method by which the heart pumps blood – should take their PVCs seriously and consult a cardiologist regarding lifestyle modifications. These include cutting down on caffeine, alcohol and smoking, reducing stress and anxiety, and getting enough rest. A cardiologist might prescribe medications to slow the heartbeat, such as a beta blocker. If you have frequent PVCs even if do not have other signs, you should see an expert in cardiology. These irregular heartbeats could point to problems with the structure of your heart or other health conditions and, over time when they happen frequently enough, they can weaken the heart muscle. Most people with PVCs don't experience any issues. They would like to know if rapid heartbeats, or the skipping of heartbeats is normal. Diagnosis PVCs can feel like heartbeats that are fluttering particularly if they're frequent and intense. Patients who have a lot of them may feel they're about to faint. They can also occur with training, even though many athletes who suffer from them don't have issues with their heart or health. PVCs could show up in tests such as an electrocardiogram (ECG) or Holter monitor. These patches contain sensors that record electrical impulses coming from your heart. A cardiologist could also employ an echocardiogram, which uses ultrasound to look at the heart and determine how it's functioning. A doctor can often tell the presence of PVCs by conducting a thorough examination and taking a medical history. Sometimes, they may not be aware of them until they examine the patient for different reasons, like after an accident or surgery. Ambulatory ECG monitoring systems can assist in detecting PVCs and other arrhythmias, and could be utilized when there is a concern of cardiac disease. If your cardiologist finds that your heart is structurally normal, reassurance is the only remedy required. However, if your symptoms are bothersome or make you feel anxious, staying away from alcohol, caffeine, and other decongestants and reducing stress can help. Regular exercise and maintaining a healthy weight, and drinking enough fluids can all help to reduce the frequency of PVCs. If your symptoms persist or severe, talk to your physician about the medications that could help control the symptoms. Treatment If PVCs are rare or don't cause symptoms, they do not usually require treatment. If you experience them frequently, your doctor may want to look for any other heart problems and recommend lifestyle changes or medications. You may also undergo an operation (called radiofrequency cathode ablation) to eliminate them. If you have PVCs, the electrical signal that triggers your heartbeat begins somewhere outside of the sinoatrial node (SA node) located in the upper right corner of your heart. This can cause your heart to feel as if it skips beats or has extra beats. It's not known what causes these symptoms, but they're frequent in those with other heart conditions. PVCs can become more frequent as you age, and they could be more frequent during exercising. A doctor should perform an ECG as well as an echocardiogram on a patient who has frequent and painful PVCs to identify structural heart conditions. They may also perform an exercise stress test to see if the extra beats are due to physical activity. To find out whether there are other reasons for the extra beats the heart catheterization or a cardiac MRI is possible. Most people with PVCs do not suffer from any complications and can lead a normal lifestyle. However, they can increase the risk of developing dangerous heart rhythm issues particularly if you have certain patterns of them. In certain cases, it means that your heart muscle gets weaker and is unable to pump blood throughout your body. Regular exercise and a healthy diet can reduce your chances of developing PVCs. You should avoid foods that are high in fat and sodium, and you should also reduce your intake of caffeine and tobacco. It is also important to get enough rest and reduce stress. Certain medications can increase the risk of developing PVCs. If you're taking one of these drugs it's crucial to follow the doctor's advice regarding eating healthy, exercising and taking your medication. In studies of patients with PVC burdens that are excessive (more than 20% of heartbeats), a higher rate arrhythmia-induced myopathy in the heart was observed. This can lead to the need for a heart transplant in some patients.
