What changes that occur in an ECG demonstrate ischemia late in the ischemic cascade? The term fibrillation refers to an irregular, ineffective heartbeat. Is ventricular fibrillation more or less serious than at
What is heart rate? Define it with physiological details. How does the ECG vary and what is occurring during these conditions: junctional rhythm, second degree heart block and ventricular fibrillation? Explain the significance of each wave on an EKG. The term fibrillation refers to an irregular,...
originating. This can be determined by the morphology of the QRS complex. For example, VT that has a LBBB morphology must come somewhere from the right ventricle; this is because the electrical potential takes a long time to reach the left ventricle, similar to what occurs with ...
The signal causes your atria to contract so blood moves into your ventricles. It then moves down to another part of your heart called the atrioventricular (AV) node. This tells your ventricles to contract and move the blood along. What happens in ventricular tachycardia?
Ventricular tachycardia (VT)refers to a heart rate greater than 100 beats per minute, which usually begins in the ventricles. It can be classified into various ways based on duration, morphology, and hemodynamic effect. For example, there are two types of VT based on duration as sustained...
Step-by-Step Solution:1. Understanding the Term "Tachycardia": - Tachycardia refers to a medical condition related to the heart's rhythm. It is important to know that this term is associated with the rate a

Also, the heart rate is elevated to a rate far in excess of what would be normally expected from such stimuli.Usually the excitable focus discharges repetitively over a long period of time to produce more continual ventricular tachycardia associated with ...
What is claimed is: 1.A method of treating ventricular tachycardias with an implanted device, comprising:delivering tiered antitachycardia pacing (ATP) through a progression of different vectors, at least one of which being partially defined by a housing of the implanted device; wherein the ATP ...
What is claimed is: 1.A system comprising:an implantable medical device including:a right ventricular pacing channel configured to provide a first pacing energy to a right ventricle; anda left ventricular pacing channel configured to provide a second pacing energy to a left ventricle; anda processor...
