Rate-corrected QT intervals using Bazett's formula. Critical for detecting drug-induced arrhythmias and Long QT Syndrome.
Mean QTc
--ms
Calculating...
Max QTc (Worst Lead)
--ms
Clinical Threshold
>500ms = CRITICAL
Male: >470ms, Female: >480ms
💓 ST/T Ratio Analysis - Hyperacute T-Wave Detection
Detects the EARLIEST sign of acute MI (0-30 minutes). Hyperacute T-waves appear BEFORE ST elevation.
Mean ST/T Ratio

T-Wave Amplitude
--mV
Clinical Threshold
<0.20 = Hyperacute
Negative = de Winter pattern (LAD occlusion)
