On the monitor patient had wide-complex tachycardia. The following 12-lead was obtained: What do you think? Differential is ventricular tachycardia versus supraventricular tachycardia with aberrancy versus sinus tachycardia with a aberrancy.

Why is this a left bundle branch block? We see a SR with broad QRS complexes (more than 120 ms). These are positive in the leftward leads I and aVL and in V5 and V6. In the more rightward leads III, aVR, and V1-V3, the QRS complexes are predominantly negative with deep S waves. This is a typical LBBB pattern.

Newly published research proves that it's possible to treat high blood pressure by using specially engineered Lactobacillus paracasei to produce a protein called ACE2 in the gut, reducing gut angiotensin II and, in turn, lowering blood pressure. The study, done in lab rats that are predisposed to hypertension and unable to naturally produce ACE2, opens new doors in the pursuit of harnessing our body's own microbiome to regulate blood pressure.

Percutaneous coronary intervention (PCI) is widely adopted to treat chronic coronary artery disease. Numerous randomised trials have been conducted to test whether PCI may provide any prognostic advantage over oral medical therapy (OMT) alone, without definitive results.

Rate vs Rhythm Control in Atrial Fibrillation Rate vs rhythm control as a management strategy in atrial fibrillation has been a long standing topic for debate. Though at one look rhythm control would appear to be the ideal strategy, long term adverse effects of the currently available medications for rhythm control is the often cited down side. AFFIRM [1] and RACE [2] trials were the main reason for the debate as they failed to show any benefit for the rhythm control strategy.

Catheter ablation of ventricular tachycardia (VT) is an important therapy to reduce morbidity associated with both infarct-related and non-ischemic cardiomyopathies1-4. Although activation and entrainment mapping of VT allow detailed assessment of the VT circuit and optimal locations for ablation, in many cases VTs are non-inducible, not sustained, or not hemodynamically tolerated.
