1.	In the detection of the waveform of ECG signal, a wave is considered as a T wave if _______(a) It occurs within a 120 ms interval(b) Its peak occurred within 1/6th the R-R interval(c) It occurs within a 200 ms interval(d) Its peak occurred within 1/3rd the R wave heightThis question was posed to me in homework.The question is from Central Monitors in section Patient Monitoring System of Biomedical Instrumentation
Answer» Right answer is (c) It occurs within a 200 ms interval Explanation: AT wave following a QRS is also searched. A wave is CONSIDERED as a T wave if (i) it occurs within a 200 ms interval, (ii) its peak occurred within 1/3rd the R–R interval +80 ms or within 240 ms whichever is greater, following the preceding R wave, and (III) its HEIGHT is half the height of a NORMAL R wave.
