These extra beats aren't usually risky, and they may go away by themselves. Doctors will monitor your heartbeat and also check other vitals signs. They may order a Holter Monitor that records the electrical impulses of your heart over a span of 24 to 48 hours. They may also request blood tests to check the levels of electrolytes and thyroid hormones. Diagnosis PVCs are caused by electrical impulses which misfire through the SA node, which is a structure located in the lower chambers of the heart. This delays the next heartbeat, causing a feeling of skipped beats or fluttering in the chest. PVCs may occur alone, or in repeated patterns. Two consecutive PVCs are known as doublets, while three or more consecutive PVCs constitute the condition known as ventricular tachycardia (VT). Some people have no symptoms, while others experience palpitations. It could be an unsteady heartbeat or a rapid heartbeat. Other common symptoms are tiredness and dizziness, as well as a feeling of being sick. Many people who experience occasional PVCs don't need any treatment. If someone is experiencing frequent episodes, doctors might suggest a change in the way of life or diet, such as limiting alcohol, caffeine and stress. They can prescribe medications such as beta-blockers or calcium channel blockers that lower blood pressure and slow down the heart rate. Doctors will ask about the patient's medical history and conduct a physical exam to check their general health. They can also employ a Holter monitor to track the heart's rhythms for longer durations or an electrocardiogram which captures a picture of the electrical activity in the heart. In certain cases doctors may require blood tests to look for an electrolyte imbalance or toxic effects from drugs. A pvc doctor might refer a patient to an electroph
