Please can you help me. I’ve been having very fast heart

Dear customer, it is a pleasure to be able to assist you today, I am very sorry for the health situation you have been experiencing with all that you are telling me, I want to tell you that I have seen the electrocardiogram you sent me and indeed you have a tachycardia but this tachycardia is totally benign and has no other type of alteration in the electrocardiographic trace that indicates the presence of something abnormal or malignant, however, all these studies should always be complemented with more specific analyses such as a 24-hour cardiac holter, which is like an electrocardiogram that is performed during 24 consecutive hours while you carry out your normal day-to-day activities in your daily life, together with an echocardiogram and a stress ergometry that is practically a 4k video of your heart and a study that helps to determine the functioning of your heart when it is subjected to physical effort, respectively, for now with propanolol the situation should improve, one of the non-pharmacological ways to decrease the heart rate is carotid massage which is performed by placing the carotid pulse in the right lateral region of the neck and massaging in a circular way very gently without making a sudden or aggressive pressure, also taking a large inhalation of air and releasing that air as slowly as possible can help reduce the heart rate this is called valsalva maneuver and is often widely used to improve such situations which will enhance the effect also of propanol, I would like to keep me abreast of your case, I will be happy to assist you and guide you in everything I can, I will be attentive to any additional questions about it.

I understand, Dear, with the measures I have indicated the situation should improve satisfactorily.
