Would ANS dysfunction cause sinus tachycardia or another type of arrythmia? Would it cause elevated epinephrine?
Dysrhythmia. The elevated epinephrine levels from whatever, causes the arrhythmia and not vice versa as a rule. I would look for other causes like anxiety, stress, fever, anemia,caffeine,alcohol,nicotine,hyperthyroidism,etc before attributing the condition to ANS. Your cardiologist and personal physician are best qualified to evaluate the dysrhythmia and its causes however.
Had 14 day loop and had sinus tachycardia with heart rates 55-180bpm. Also the 180 occurs when sleeping or lying in bed. Cardiologist not sure why tach occurs every night. Elevated epinephrine? Ideas?
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. Read more...
