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

What is the difference between arrhythmia and atrial fibrillation (AFib)?
Arrhythmia is a general term for any irregular heartbeat, while atrial fibrillation (AFib) is a specific type of arrhythmia where the heart's upper chambers beat irregularly and too fast.
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 the difference between PVCs and AFib?
Premature ventricular contractions (PVCs) are extra heartbeats that originate in the ventricles, while atrial fibrillation (AFib) is an irregular and often rapid heart rhythm that originates in the atria. PVCs are usually harmless, while AFib can increase the risk of stroke and other complications.
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.

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 an atrial fibrillation?
Atrial Fibrillation (AF) is the most common sustained arrhythmia encountered in clinical practice, yet its presentation and progression vary widely between patients. From silent AF discovered incidentally to rapid ventricular response causing hemodynamic collapse, each case offers a unique learning opportunity. Are you a cardiologist, electrophysiologist, medical researcher, or healthcare professional with a compelling clinical case to share? Submit your Atrial Fibrillation Case Reports to a trusted academic platform powered by Bristol Publishers and reach a global medical audience. Atrial fibrillation (AF) remains one of the most common cardiac arrhythmias worldwide, contributing significantly to stroke risk, heart failure, and cardiovascular mortality. With evolving treatment strategies such as catheter ablation, anticoagulation therapy, and novel antiarrhythmic drugs, documenting real-world clinical experiences is more important than ever. Publishing detailed Atrial Fibrillation Case Reports helps advance evidence-based practice and supports clinicians in managing complex AF presentations.
How can you differentiate between atrial fibrillation (AFib) and premature ventricular contractions (PVCs)?
Atrial fibrillation (AFib) is an irregular and rapid heartbeat originating in the upper chambers of the heart, while premature ventricular contractions (PVCs) are early extra heartbeats originating in the lower chambers. AFib may feel like a fluttering or racing heart, while PVCs may feel like a skipped or extra beat. A doctor can use an electrocardiogram (ECG) to diagnose and differentiate between the two conditions.
What is the difference between ventricular and atrial rate?
The atrial rate refers to the number of electrical impulses originating from the atria, while the ventricular rate is the number of impulses generated that reach the ventricles and trigger contraction. In a normal heart, these rates are typically equal, but in certain arrhythmias, such as atrial fibrillation, the atrial rate may be significantly higher than the ventricular rate. This discrepancy can affect cardiac output and overall heart function. Understanding both rates is crucial in diagnosing and managing various cardiac 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 sotalol af and sotalol hcl?
Sotalol AF refers to the formulation specifically indicated for atrial fibrillation (AF), while sotalol HCl refers to the general formulation of sotalol hydrochloride used for other arrhythmias like ventricular tachycardia. The dosing and monitoring of sotalol AF may be different due to its specific use for AF.
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 is Atrial Kick on the EKG?
Atrial kick refers to the additional volume of blood that the atria contribute to the ventricles just before ventricular contraction, primarily during the late phase of atrial systole. On an EKG, this phenomenon is not directly visible, but it influences the overall ventricular filling and can be inferred from the relationship between the P wave (representing atrial depolarization) and the following QRS complex (representing ventricular depolarization). In conditions like atrial fibrillation, the loss of the atrial kick can lead to decreased cardiac output.
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.
