Figure 7

(A) Actual recording of the SKNA in Lead I and ECG in the patient with single VT episode. The onsets of VT are indicated by red dotted lines, and the terminations of VT are indicated by blue dotted lines. SKNA discharges (downward arrows) were observed before VT onset. (B) Actual recording in the patient with early recurrence of VT episodes. Multiple SKNA bursts occurred during sinus rhythm between VT episodes and also during VT. SKNA, skin sympathetic nerve activity; iSKNA, integrated SKNA; VT, ventricular tachycardia; ECG, electrocardiogram; HR, heart rate.
