Had A Racing Heart And Slowed Down Through Breathing. Should I Be Concerned?
1. An unprovoked racing of heart indicates heart rhythm disorder. If it is associated with loss of consciousness/ chest pain/ blackout, then it is an emergency and should be looked into at priority. Otherwise, the most appropriate way to look at a heart rhythm disorder is to identify that what kind of rhythm is it. This can be best done by an electrocardiogram (ECG) taken at time of racing of heart. At times when it is not feasible, we can apply a 24 hour ECG monitor (Holter monitor) provided that likelihood of occurrence of event in 24 hours is high. If that is also not feasible, we do a generalized small work-up which includes a thorough clinical examination, resting ECG, an echocardiogram (ECHO or ultrasound of heart), blood profile mainly including thyroid hormone levels & hemoglobin. If all come out to be normal, we wait for the next event and tend to record ECG at that time.
2. The reasons for apparent undue shortness of breath may be cardiac and non-cardiac. Cardiac disorders mainly include disorders of heart pumping, disorders of relaxation of heart, valvular abnormalities, anginal heart disease, high blood pressure and its effects on heart etc. Non-cardiac issues include sedentary life style, obesity, low hemoglobin (anemia), renal failure, lung diseases, any severe systemic illness. Sedentary life style is a very important factor in a number of patients. Normally such patients require a thorough cardiac and systemic examination by your doctor followed by a few tests including ECG, X-ray chest, blood profile, pulmonary function test (guided by examination).If it all comes to normal or inconclusive, an Echocardiaogram should be done. I hope this much of work-up will give enough clues that in which direction should we proceed.
Hope this gives some insight into the issues.
Feel free to discuss further.
