Screen capture ECG traces. a. Screen capture ECG trace showing occurrence of multiple VPCs and variable rate within a 6-min period whilst observed resting, undisturbed in stable. The 24-h ECG trace was characterised by multiple runs of resting sinus tachycardia and multiform VPCs (>100). Gain 5Â mm/mV, feed 10Â mm/s. b. Screen capture ECG trace focused on area illustrating two ventricular premature complexes highlighted with an asterix (*). Gain 20Â mm/mV, feed 25Â mm/s
