Hi friend, Welcome to Health Care Magic THE FIRST STEP IS TO SEE A CARDIOLOGIST / Irregular heart beats need to be DOCUMENTED by ElectroCardioGram (EKG). Standard ECG records the electrical activity of the heart, for a few seconds. It can detect the arrhythmia occurring during that time only. If the episode occurs randomly or precipitated by a specific activity like exercise, one needs Holter or event monitor. Anaemia / Anxiety / Alcohol / Tobacco (smoking) / Caffeine (too much tea, coffee, cola) / Fever / Infection / Pain / Stress / Thyroid / Vitamin D, calcium, magnesium / Medicines like Phenylephrine used for ‘cold’; Salbutamol used for asthma and so on / may be responsible.... / Illicit ‘drugs’ like Amphetamine are notorious to cause abnormal beats / At times, abnormal nerve paths in the heart (bypass tracts) or disease of the conduction system may be responsible! ECHOcardiogram / LABORATORY work-up – may all be necessary for further assessment and assistance. / You may even need Electro Physiological Studies (EPS) The treating doctor may suggest them depending on need, based on his assessment of the situation. Take care Wishing speedy recovery God bless Good luck
