For the last month and a half I have been having a sensation of pressure in the centre of my chest, sometimes with the feeling of my heart beat, but mostly just the chest pressure. It happens when I am walking, standing, sometimes sitting.  It is most frequent in the afternoon and evening. At first it would just be for a moment, but now is lasting for half an hour or longer.  I am not particularly anxious about anything when this happens; do you think it is low blood pressure?
Hi, Chest pressure and heaviness in the chest may be due to infection or arrhythmia or episodic asthma or myocardial infarction etc. Until examination is done it is difficult to say what it is. Get it done ECG, echocardiography, hemoglobin and serum electrolytes. Please consult your doctor he will examine and treat you accordingly. Hope I have answered your query. Let me know if I can assist you further.
