<bot>: Hello. Thank you for your question and welcome to Chat Doctor. I carefully read your query. The symptoms you are describing with tremors of limbs and jaw, dizziness, irritability and irregular heart beats, make me suspect for a thyroid gland dysfunction. Therefore, I recommend that you do a full thyroid control:- blood levels of TSH, fT3, fT4;- ultrasound of the thyroid gland. Furthermore, this heart beat that you are experiencing, can be irregular. In this case, the highest probability is that we have to deal with a supraventricular arrhythmia, probably atrial fibrillation (instead of atria being contracted in harmony with the cardiac cycle, their contraction is uncontrolled, and they do not function properly to propel the blood into the ventricles). This is a benign arrhythmia, but if more than 48 hours on this arrhythmia, atria can generate little blood clots (thrombi) due to not contracting properly. Thus, I suggest you to do an EKG, echocardiogram and a 24-hour Holder rhythm monitor registration, to confirm or exclude this diagnosis and, also to start treatment either to achieve rate control or rhythm control. You can further discuss these matters in details with your treating cardiologist. I hope I was helpful. Best regards. Take care.
