WebA normal adult heartbeat is 60 to 100 beats per minute (BPM). Junctional rhythm can cause your heartbeat to be slower than normal ( bradycardia ), or faster than normal ( tachycardia ). Types of junctional rhythm include: Junctional bradycardia: Less than 40 BPM. Junctional escape rhythm: 40 to 60 BPM. Accelerated junctional rhythm: 60 to 100 BPM. WebThe PR segment elevation and depression The PR segment is not affected in STEMI, whereas acute pericarditis often causes PR segment depression. Such depressions occur in most leads, except from lead V1, which often shows PR segment elevation. Troponin leakage in acute pericarditis Elevated troponins are common in acute pericarditis.
