Every so often my heart will tighten as though I am scared when I am not and my rate will speed up considerably. It often occurs at random intervals and the tightening sensation only lasts for a few seconds when ever it does occur. From what I can tell, nothing specific triggers it, however it often makes me gasp or become short of breath until the sensation subsides.
Hi, After going through your case I want to know-1) Age & gender.2) Presence of diabetes, blood pressure problem, cholesterol problem.3) Family history of heart disease.4) Habits like smoking, alcohol.5) Any medicines are you on. You should not ignore these symptoms. There might be following causes for it -1) Heart attack.2) Cardiac arrhythmia (Electrical disturbances in conduction system of heart). 3) Anxiety if there are any mental stress. Though it needs to be confirmed by evaluation. I will advise you -1)You should visit emergency care during episode at that time electrocardiogram (ECG) may give important information. 2) Resting ECG, electrophysiologist study of heart, 2DEcho of heart.3) Blood levels of cardiac enzymes Troponin I/T, CLIMB.4) Tests for kidney function.5) Thyroid function. So better to consult cardiologist as early as possible. I think this may helpful to you. If found helpful vote helpful. Feel free to write back your queries if any.
