Greetings and welcome to justanswer,
what are your symptoms?
what is the heart rate?
is there any st-t wave depression or elevation?
did you consult a doctor yet?
do you have chest pain?
Thank you for the information,
The ekg shows that you have sinus tachycardia that means your heart rate is more than normal.The normal resting heart rate is between 60-100 bpm and yours is slightly higher than the normal range.
The non-specific st-t wave changes may be caused by various causes like anxiety, electrolyte imbalance, ischaemic heart disease, pancreatitis, hypothyroidism, etc.
You should have relevant investigations done like coronary angiography, serum electrolytes, 2d echo of heart, serum cortisol levels, thyroid profile to know the associated abnormality after consulting your doctor/cardiologist.
The treatment depends on the underlying cause.You should also monitor your blood pressure and if high start the antihypertensive therapy.The beta blockers like propranolol may be helpful in controlling the heart rate.
