Evaluation of cardiac symptoms by trans-telephonic electro-cardiographic monitoring (TTEM): preliminary experience.

ABSTRACT

Between May 1996 and May 1997, a total of 398 patients (321 males, 77 females) were registered at our institute for trans-telephonic electro-cardiographic monitoring (TTEM). Their age ranged from one month to 95 years. Almost two-third (67%) of patients were from Delhi and one-third (33%) from other places in India and neighbouring countries. Clinical profile of these patients was post-bypass surgery, post-myocardial infarction, chest pain for evaluation, post-percutaneous transluminal coronary angioplasty, chronic stable angina, evaluation of palpitations, arrhythmias, and pace-maker follow-up. Out of 664 symptomatic transmissions, 568 (86%) were received for cardiac symptoms and 96 (14%) for non-cardiac symptoms. Seventy-nine percent patients had chest pain or palpitations at the time of transmission, whereas 21 percent had other symptoms like chest discomfort, breathlessness or dizziness. The electro-cardiograms were transmitted within one hour of the onset of chest pain in 84 percent, palpitations in 78 percent and dizziness in 75 percent. Of patients with symptomatic transmissions, 628 (95%) required either reassurance or drug-dose adjustment and outpatient department review. Only 36 (5%) patients were hospitalised as an emergency, and out of these only 19 (3%) needed acute management. In conclusion, trans-telephonic electro-cardiographic monitoring is a very convenient and an 'all-time-available' monitoring facility for establishing patient-physician contact in the shortest time. It is useful in rendering instant advice for hospitalisation in emergency situations while avoiding unnecessary visits to the hospital.
