What is the difference between PAC (Premature Atrial Contraction) and PVC (Premature Ventricular Contraction) on an ECG?
Premature Atrial Contraction (PAC) occurs when the heart's upper chambers contract too early, causing an abnormal heartbeat on an ECG. Premature Ventricular Contraction (PVC) happens when the heart's lower chambers contract prematurely, also leading to an abnormal rhythm on an ECG. The key difference is the origin of the early contraction within the heart's chambers.

What is the difference between PVC and PAC on an ECG?
On an ECG, PVC (premature ventricular contraction) is an early heartbeat originating from the ventricles, while PAC (premature atrial contraction) is an early heartbeat originating from the atria. Both can indicate potential heart rhythm abnormalities.
What are the key differences between premature atrial contractions (PAC) and premature ventricular contractions (PVC) as seen on an electrocardiogram (ECG)?
Premature atrial contractions (PAC) are early heartbeats originating in the atria, while premature ventricular contractions (PVC) are early heartbeats originating in the ventricles. On an ECG, PACs typically show a P wave that looks different from the normal sinus rhythm, while PVCs show a wide and bizarre QRS complex.
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.
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 are the key differences between ECG findings in patients with PVCs and PACs?
Patients with premature ventricular contractions (PVCs) typically show wide and bizarre QRS complexes on an ECG, while patients with premature atrial contractions (PACs) usually display abnormal P waves. Additionally, PVCs often occur earlier than expected in the cardiac cycle, while PACs tend to occur later.

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 ventricular fibrillation and arrhythmia?
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 isotonic and isometric contractions?
An Isotonic muscle contraction is a muscle contraction that makes your limbs move whereas an Isometric contraction is a muscle contraction where the limbs stay static
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 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.
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 located between the two ventricular chambers and the large arteries that carry blood away from the heart when contraction occurs?
The mitral valve is located between the left atrium and left ventricle, and the aortic valve is located between the left ventricle and the aorta.
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 the difference between extension and contraction?
Extension is when the price goes up and no other factor changes. Contraction is when the price goes down and no other factor changes.
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.
