Tachycardia: Did the cardiologist state what type of tachycardia the rhythm of 180 beats per minute was? Supraventricular or ventricular and how long these tachyarrhythmias lasted?Anxiety usually doesn't cause the heart to beat at 180/min. Checking for hyperthyroidism and for a pheochromocytoma would be advisable before attributing these episodes to anxiety reactions panic attacks. ?See an endocrinologist.
