4. Figure 3
ECG findings in syncope. “Red light” might suggest malignant arrhythmia in certain contexts; “yellow light” might require a nonurgent evaluation in cardiology; “green light” indicates normal variants with no further management needed. AV, atrioventricular; bpm, beats per minute; ECG, electrocardiogram; PVC, premature ventricular complexes. ∗Manual measurement using tangent; see Figure 4.

5. Figure 4
Measuring the QT interval. QTc is the heart rate corrected using the Bazett formula with use of the preceding RR interval. To determine QT, a tangent is drawn to the steepest slope of the last limb of the T wave in lead II or V5. The end of the T wave is the intersection of the tangent with the baseline.
