What is the rate range for junctional tachycardia?

60-100
80-140
100-160
100-180

The correct answer is: 100-180

Junctional tachycardia is characterized by a heart rate that typically ranges from 100 to 180 beats per minute. This type of tachycardia occurs due to re-entry circuits or abnormal automaticity originating in the atrioventricular (AV) junction, where electrical impulses are generated. The heart rate in junctional tachycardia is often faster than normal, indicating a disruption in the electrical conduction system, particularly when the usual pacemaker (the sinoatrial node) is bypassed or overridden. Understanding that the normal heart rate is 60-100 beats per minute, any rate above that can be classified as tachycardia, with junctional tachycardia being specific to the rate range mentioned. The other provided options do not accurately represent the typical ranges of junctional tachycardia, reinforcing the importance of recognizing the defining characteristics of this arrhythmia.
