The key difference between AV block 1 and 2 is that AV block 1 is due to a delay in the conduction of atrial impulses to the ventricles, while AV block 2 is due to a blocking of the conduction of some of the atrial impulses to the ventricles. Heart block is also known as […]

The key difference between PAC and sinus arrhythmia is that PAC is extra heartbeats that begin in one of the heart’s two upper chambers called atria, while sinus arrhythmia is an irregularity in the heart rhythm that begins at the sinus node of the right atrium. An arrhythmia is a condition where the heart rhythm is abnormal. […]

The key difference between ablation and cardioversion is that ablation is a procedure that destroys small parts of tissue inside the heart to keep the faulty electrical signals in the heart from triggering irregular beats, while cardioversion is a procedure that gives a mild electric shock to reset the heart to a regular rhythm from […]

The key difference between unstable angina and myocardial infarction is that unstable angina is a medical condition that results in chest discomfort without warning due to an insufficient flow of blood and oxygen to the heart, while myocardial infarction is a medical condition where the heart muscles begin to die because it is not getting […]

The key difference between PAC and PVC is that PAC is a type of premature electrical activation originating in the upper chambers of the heart, while PVC is a type of premature electrical activation originating in the lower chambers of the heart. An arrhythmia is an irregular heartbeat or heart rhythm, meaning that the heart is out of its usual […]

The key difference between heart murmur and arrhythmia is that heart murmur is an extra and unusual sound in heartbeats, while arrhythmia is an irregular heartbeat rhythm. Heart murmur and arrhythmia are two health conditions associated with the heart. A heart murmur is common and not always due to an illness or disorder. However, arrhythmia […]

The key difference between asystole and PEA is that asystole is a type of cardiac arrest in which the heart stops beating entirely, while PEA is a type of cardiac arrest in which the heart stops beating to some extent but not entirely. Cardiac arrest occurs when the heart stops beating or stops pumping suddenly […]

The key difference between angina pectoris and myocardial infarction is that angina pectoris is a condition that causes chest pain or discomfort when the heart is not receiving enough oxygen-rich blood, while myocardial infarction is a condition that can cause permanent heart damage and even death due to a lack of blood flow resulting from […]

The key difference between sinus tach and SVT is that sinus tach is a type of tachycardia that presents with a heart rate of 100 to 150 beats per minute, while SVT is a type of tachycardia that presents with a heart rate of 151 to 250 beats per minute. Tachycardia is a medical condition […]

The key difference between heart palpitations and arrhythmia is that heart palpitations are short-lived feelings of the heart racing, fluttering, thumping, or pounding in the chest, while arrhythmia is an abnormal heart rhythm where the heart beats irregularly. Heart muscle functions by pumping blood, oxygen, and important nutrients to all parts of the human body. […]
