Tachycardia-dependent bundle branch block (TDBBB) can affect either ventricle in the heart, and occurs when the heart's rate of contraction reaches an elevated level and becomes uncoupled from the heart's refractory period (the time it takes for a cardiac cell to "reset" for future contraction).
A right bundle branch block (RBBB) is a heart block in the right bundle branch of the electrical conduction system. [1] During a right bundle branch block, the right ventricle is not directly activated by impulses traveling through the right bundle branch. However, the left bundle branch still normally activates the left ventricle.
Kamath says it can cause intermittent chest pain or sharp, tearing chest pain that often radiates to the shoulders and the back. It more often happens to men between the ages of 60 and 80.
A right bundle branch block typically causes prolongation of the last part of the QRS complex and may shift the heart's electrical axis slightly to the right. The ECG will show a terminal R wave in lead V1 and a slurred S wave in lead I. Left bundle branch block widens the entire QRS, and in most cases shifts the heart's electrical axis to the ...
Another possible cause of chest pain that you can reproduce easily is costochondritis, which happens when the cartilage around your ribs becomes inflamed, the Mayo Clinic says. And it most often ...
Dozens of conditions can cause chest pain on the right side. Some are directly related to the right side because an organ such as a lung is there, or it could be referred pain.
Unfortunately, the answer is quite broad—there are so many medical conditions that can cause pain in the chest. It can be as simple as a pulled muscle or as complicated as pulmonary embolism ...
The different types of split S 2 can be associated with medical conditions: Split during inspiration: normal. [3] (See above) Wide splitting: seen in conditions that delay RV emptying (pulmonic stenosis, right bundle branch block). Delay in RV emptying causes delayed pulmonic sound (regardless of breath); it is an exaggeration of normal ...
