For the past few days Ive had constant palpitations and irregular heart beats. What can it be?
Worst case: heart disease, heart attack (could have happened already with the irregular beats the result), conduction abnormality in heart, endocarditis (infection of cardiac muscle), infection and/ or calcified lesions on the heart valve(s). Best case: benign arrythmia (something that is “normal” or usual for you, and not causing any problem), palpitations from stress or caffeine or other medicine.
