Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles). D igoxin: Helps slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles).
Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
Having V-tach is really dangerous and can develop into another dangerous rhythm Ventricular fibrillation, both of these require immediate medical attention. VT is treated with cardioversion, either drug cardioversion or electrical cardioversion. Drug cardioversion involves a drug treatment that aims to lower the heart rate back to a normal rhythm.
However, if a patient is confirmed to be in pulseless ventricular tachycardia "v-tach" or ventricular fibrillation "v-fib", then a shock is delivered immediately upon connection of the pads. In this application, electrical cardioversion is more properly termed defibrillation.
Many modern ICDs use a combination of various methods to determine if a fast rhythm is normal, supraventricular tachycardia, ventricular tachycardia, or ventricular fibrillation. Rate discrimination evaluates the rate of the lower chambers of the heart (the ventricles ) and compares it to the rate in the upper chambers of the heart (the atria ).
Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1] This is followed by sudden cardiac death in the absence of treatment. [2]
Initially, objects are allocated in "to space" until it becomes full and a collection cycle is triggered. At the start of the cycle, the "to space" becomes the "from space", and vice versa. The objects reachable from the root set are copied from the "from space" to the "to space".
However, ventricular tachycardia and ventricular fibrillation remain the most important causes of sudden death following spontaneous restoration of antegrade flow. [6] Prior to the modern practice of percutaneous coronary intervention for acute coronary syndrome , pharmacologic thrombolysis was more common and accelerated idioventricular ...
