What is the difference between ventricular fibrillation and arrhythmia?
Wiki User
∙ 10y ago
Ventricular fibrillation (V fib, VF) is a fatal dysrhythmia that occurs as a result of multiple weak ectopic foci in the ventricles. In other words, there is NO coordinated atrial or ventricular contraction and NO palpable pulse.
Ventricular tachycardia (VT or V tach) have three or more PVCs with a rate of >100

∙ 10y agov-fib is a more serious and potentially fatal arrhythmia, it is an arrhythmia though so they are one of the same

∙ 12y agoVentricular fibrillation is very serious and leads to death if not treated promptly, normally by means of a defibrillator.

What is the difference between Left Ventricular Hypertrophy and Left Ventricular Dysfunction?
LVH (Left Ventricular Hypertrophy) is (anatomical) structural condition and status of the heart, while Left Ventricular Dysfunction is disturbance in physiological functions and status of heart.
What is heart Fibrillation?
Atrial fibrillation is where the electrical impulses within the atria become very rapid and irregular. Atrial rates are usally between 300- 400 BPM or more. How it can happen: 1) Electric shock 2) ion imbalance within heart cells 3) Re- entry pathway. For more information please contactHeartquestionsanswerd@hotmail.co.uk We will answer your question for FREE however use this information as a guide ONLY. I am NOT a doctor but I have been studying the heart for many years and the information here is up=to date.Fibrillation is a medical term and refers to the quivering of a muscle, usually in the heart, as opposed to it contracting properly. Due to uncoordination of the muscle fibrils. Common terms heard are atrial and ventricular fibrillation, the first meaning that the atria of the heart (chamber that fills with blood) is not working well. When ventricular fibrillation occurs, only a small amount of blood is pumped out of the heart. This is the more serious of the two conditions.
What is the minimum amount of current enough to kill a man?
100mA of 60Hz AC current for three seconds can cause ventricular fibrillation. From "Deleterious Effecst of Eelctric Shock", Charles F. Dalziel.
What is the difference between supra ventricular tachycardia and paroxysmal supra ventricular tachycardia?
PSVT are those SVTs which are sudden, abrupt, almost immediate and unexpected onset and are more regular as well... PSVT is just the type of SVT..
What are the differences between synchronous and asynchronous cardioversion?
Synchronus cardioversion is when shock is delivered on QRS portion of the heart cycle (time when ventricle depolarises). It is used when pulse is present in a patient usually greater than 150/min and sign and symptoms usually of tachycardia. Like in Atrial Fibrillation. But in case of asynchronus cardioversion shock can be given at any time of heart cycle. Pulse is absent like in Ventricular Fibrillation.
Do the ventricles have the same rate as the atria in atrial fibrillation?
No. In atrial fibrillation, the atria have regional depolarizations at a rate of over 300 per minute. Fortunately, the atrioventricular node prevents the ventricular rate from being this high as we would die from lack of cardiac output. There are conditions where the ventricles are depolarized at a rate approximating the atrial depolarization - these include the Lown-Ganong-Levine and Wolff-Parkinson-White syndromes, and consist of abnormal tracts between the atria and ventricles around the AV node.
What are the valves between the atria and the ventricles called?
Atrio-ventricular valves
What does a long QT interval on ECG mean?
It is a lengthening of the amount of time between depolarization of the ventricles of the heart, and the repolarization of the ventricles of the heart. The significance of this lies in the fact that the Q-T interval is a vulnerable time for the heart. Stimulation of the heart muscle during the relative refractory period (which is during the latter part of the Q-T interval) will cause a premature ventricular contraction, which may throw your heart into a dangerous dysrhythmia.
What is the difference between arrhythmia and fibrillation?
In the true meaning of the word, a= without; the only arrhythmia is asystole which is an absence of heart beats.Fibrillation is a dysrhythmia, dys= not, characterized by fast, unfocused impulses in the atria or ventricles causing the heart tissue to quiver instead of contract uniformly.NOTE: some people (even medical professional)still incorrectly inter-change the words dysrhythmia and arrhythmia. When you are taking about heart rhythms be as specific as possible to avoid mid communication.

What is the difference between heart rate and ventricular rate?
On an ECG the heart rate will match both ventricular rate and atrial rate if the heart is normal. If people have atrial fibrilation then the ventricular rate will be used on the ECG to work out the rate of the ventricular contraction and vice-versa with ventricular fibrilation. Usually both atrial and ventricular rates match so if the atria contracts at 70 BPM the ventricles will beat at 70 BPM. It is possible for the ECG machine to work out atrial or ventricular rate if needs be. Usually, however, if the ECG machine just displays heart rate then both ventricular and atrial rates match.
What are the ECG characteristics of Atrial flutter?
1- Inverted P waves (F waves) in II, III and AVF. 2- saw-tooth pattern between QRS complexes in II,III and AVF. 3- Atrial rate is 250-400 and regular but ventricular rate depends on AV node and between 60-150 and typically regular. 4- QRS is not wide 5- T waves not identifiable.
