They may order an Holter Monitor which records the electrical impulses of your heart over a time of between 24 and 48 hours. They can also request blood tests to determine your electrolyte levels and thyroid hormones. Diagnosis PVCs are caused by electrical impulses which misfire through the SA node, a structure located in the lower chambers of the heart. This causes the next heartbeat to be delayed, causing an experience similar to racing or skipped beats. PVCs can be seen as a single event, or in repeated patterns. Two consecutive PVCs are known as doublets. Three or more consecutive PVCs constitute ventricular Tachycardia (VT). Some people are not experiencing any symptoms, but others experience palpitations. It could be the sound of a beating heart or a rapid heartbeat. Other symptoms include fatigue, dizziness, or a feeling that you're unwell. Many people with occasional PVCs do not require treatment. If someone is experiencing frequent episodes, doctors might suggest a change to lifestyle or diet including a reduction in caffeine, alcohol and stress. They can prescribe medications such as beta-blockers and calcium channel blockers that lower blood pressure and slow down the heart rate. Doctors will inquire about the patient's medical history and perform a physical examination to assess their general health. They may also utilize a Holter monitor to track the heart's rhythms for longer periods of time, or an electrocardiogram, which records a snapshot of the electrical activity of the heart. Doctors may order blood tests in certain cases to determine if there are electrolyte imbalances or toxic substances in the body. Occasionally, a pvc
