Redfearn DP, Ratib K, Marshall HJ, Griffith MJ. Supraventricular tachycardia promotes release of troponin I in patients with normal coronary arteries. Int J Cardiol. 2005;102(3):521-2.
BACKGROUND
Troponin I and T are sensitive markers of myocardial injury. The presence of elevated troponin often prompts further investigation with coronary angiography.

METHODS
We present a series of patients presenting to our unit with raised troponin I and supraventricular tachycardia (SVT) that prompted coronary angiography.

RESULTS
All patients had normal epicardial vessels at angiogram, no evidence of muscle bridging or pulmonary embolism.

CONCLUSION
The presence of tachycardia sufficient to warrant hospital admission can raise troponin, and this should be viewed in context when a decision on angiography is to be taken.
