Bundle branch blocks (BBBs) are conduction delays within the ventricles of the heart. You can see the effects of these delays on an electrocardiogram (ECG), which shows up as changes in the QRS complex.

A right bundle branch block (RBBB) means there’s a delay in the right ventricle, while a left bundle branch block (LBBB) means there’s a delay in the left ventricle.

Here, we’ll explain the ECG criteria, underlying electrophysiology, possible causes, and clinical implications of both RBBB and LBBB. We’ll also look at how our understanding of BBBs is changing, especially when it comes to acute myocardial infarction (AMI).

Knowing what’s going on in the heart is more useful than just memorizing patterns on an ECG.

When your eyes work together, you have binocular vision. This allows you to see a single, clear image and helps you with depth perception.

Sometimes, the eyes don’t align perfectly. That’s when conditions like tropia and phoria come into play. Both involve some level of eye misalignment.

The main difference between a tropia and a phoria is that with a phoria, your eyes can usually compensate to maintain single vision. A tropia, however, is a manifest misalignment that’s always present.

If uncorrected, both tropias and phorias can cause eye strain, headaches, and reduce visual performance. In this article, we’ll explore the definitions, types, and differences between tropia vs phoria, as well as potential treatments to get your eyes back on track.
