Paroxysmal SVT (PSVT) that repeatedly recurs in spite of successful conversion with adenosine
An elderly male complained of dyspnea. His pulse was regular at just under 150. BP was 110/70. There was no evidence of shock or pulmonary edema. Here is his ED ECG:There is a very rapid, wide complex tachycardia (QRS = 150 ms). There are no P-waves before the QRS's. There is a definite Right Bundle Branch Block and Left Anterior Fascicular Block pattern, so this is not VT. The bifascicular block was new. It could be a new block, or a rate-related BBB If you look closely, you can see the inverted (retrograde) P-waves. (See annotated ECG below, with arrows pointing ...

Heart rate 50/minute at rest, on medications for high BP – Any need to worry?
Medications belonging to the group of beta blockers (e.g. atenolol, metoprolol) and some medications belonging to the group of calcium channel blockers (e.g. diltiazem, verapamil), can reduce resting heart rate. A resting heart of 50/minute alone is not a reason for worry. If you have symptoms like light headedness, greying of vision or fainting of episodes, your doctor may want to reduce the dose of these medications or substitute another for control of your blood pressure. Normal heart rate for an adult is in the range of 60-100/minute. It can go down in sleep and go up with exercise and stress. (Source: Cardiophile MD)

A 12-lead was recorded during the tachycardia: There is a regular, wide complex tachycardia at rate of 170 bpm, with QRS duration of 124 ms. There are no p-waves, no AV dissociation, no concordance (QRS in precordial leads are not all in the same direction). There is inferior axis (all positive in II, III, aVF, and all negative in lead aVR. There is an initial wide r-wave in V1 and V2 (greater than 40 ms). There is a left bundle branch block mo...
