Brief Answer: See cardiologist / get examined and investigated Detailed Answer: Hi friend, Welcome to Health Care Magic If it was not heart surgery, the events are unlikely to be related… The first step is to see a Cardiologist! Racing 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, one needs Holter or event monitor. There could be several possibilities – Anaemia / Anxiety / Alcohol / Tobacco (smoking) / Caffeine (too much tea, coffee, cola) / Fever / Infection / Pain / Stress / Thyroid / calcium, magnesium / Medicines like Phenylephrine used for ‘cold’; Salbutamol used for asthma and so on - may be responsible.... / At times, abnormal nerve paths in the heart (bypass tracts) or disease of the conduction system may be responsible! A thorough history and physical examination is the first step - ECHOcardiogram / TMT (Treadmill exercise ECG) / LABORATORY work-up – may all be necessary for further assessment and assistance. Very often they are harmless / and may not need any specific treatment. Before surgery, the anaesthesiologist must have evaluated you for fitness / and in such situations, the chance of heart disease is not at all high and the prognosis is likely to be excellent… The change in taste may be from the side effects of your medicines... The treating doctor alone can suggest further based on his assessment of the situation. Good luck Take care Wishing all well God bless
