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. flagler beach bob cunninghamWebSinus arrhythmia is a kind of arrhythmia (abnormal heart rhythm). For the most common type of sinus arrhythmia, the time between heartbeats can be slightly shorter or longer depending on whether you’re breathing in or out. Your heart rate increases when you breathe in and slows down when you breathe out. flagler beach bed and breakfast floridaWebThe normal PR interval is from 120 ms to 200 ms in length. This is measured from the initial deflection of the P wave to the beginning of the QRS complex. [3] In first-degree heart block, the AV node conducts the electrical activity more slowly.
