ecg is used to monitor the electrical activity of the heart.
it will help to find out how your heart is working.
to rule out ant anomalies or conduction disturbances in the heart.
sob mostly refers to shortness of breath
and cp mostly refers to chest pain
all your symptoms suggest a lesion in your ekg and hence i would advise you to consult a cardiologist
in this regard and rule out any disease of the heart.
i would advise you to consult your emergency number if you have chest pain or if you can feel your heart beat or if you are unable to breath while sleeping.
i wish you good health.
