During pre-op testing for my father’s back surgery, the EKG showed a “bundle.” What exactly is a bundle and what does it mean for his health?
The heart's electrical activity normally starts in the heart's natural pacemaker (called the sinoatrial node), which is situated on the upper right chamber of the heart (atrium). From there the electrical impulse travels to the left upper chamber (atrium) and into the atrioventricular (AV) node. Electrical impulses travel through certain cells that are specially designed for the purpose of carrying those impulses. They carry them faster than regular heart muscle cells and are located near one another. When there are many such cells together in a bunch we call this grouping a node. From the AV node the electrical impulse travels down the bundle of His and divides into the right and left bundle branches. When the electrical impulse carrying cells are arranged in a line to carry many impulses together we call this a bundle, if it is ...
Definition Left heart ventricular angiography is a procedure to look at the left side of the heart and, sometimes, the coronary arteries. Alternative Names Angiography - left heart; Left ventriculography How the test is performed Before the test, you will be given medicine to help you relax. You will be awake and able to follow instructions during the test. An intravenous line is placed in your arm. The health care provider cleans and numbs an area on your arm or groin. A cardiologist makes a small cut in the area, and inserts a thin flexible tube (catheter) into an artery. Using x-rays as a guide, the doctor carefully moves the thin tube (catheter) into your heart. When the tube is in place, dye is injected through it. The dye flows through the blood vessels, making them easier to see. X-rays are taken as the dye moves through the blood vessels. These x-ray pictures create a "movie" of the left ventricle as it contracts rhythmically. The procedure may last from 1 to several hours. How to prep...
Left heart catheterization is the passage of a thin flexible tube (catheter) into the left side of the heart to diagnose or treat certain heart problems.
Catheterization - left heart
How the test is performed
You may be given a mild sedative before the procedure starts. The health care provider will place an IV into your arm so that you can receive medication during the procedure.
You will lie on a padded table. Your doctor will make a small surgical cut on your body, usually near the groin. Then your doctor will insert a flexible tube (catheter) through the cut into an artery. Sometimes the catheter will be placed in your arm or wrist. You will be awake during the procedure.
The doctor will use live x-ray pictures to carefully guide the catheter up into your heart and arteries. Dye will be injected into your body to highlight blood flow through the arteries. This helps the doctors see any blockages in the blood vess...
