Fig. 32.2 Heart block in aortic stenosis (AS). Elderly female, breathless, severe AS. Three P waves for every QRS complex – two are easily seen, the third is at the…

Fig. 25.2 Myocarditis. Sinus tachycardia, heart rate 91 b/min, non-specifically abnormal P wave, normal PR interval, good voltage QRS complexes throughout. T wave inversion, deep, in leads V1–3; ST depression…

Fig. 23.2 Rhythm strip from monitoring in recent syncope. The heart slows, then a run of ventricular tachycardia (VT) starts (fast broad complex tachycardia, showing independent P wave activity). Syncopal…

Fig. 33.2 ECG in a patient with mitral stenosis. Atrial fibrillation, with very coarse fibrillatory waves in lead V1 – these might be mistaken for an atrial tachycardia, but running…

Fig. 21.2 Left ventricular hypertrophy (LVH). Substantial increase in the voltage of the leads looking at the left ventricle – the R wave in V5 = 33 mm (exceeding that…
