To summarize, the key difference between a jurat vs acknowledgment is that the former is used primarily when dealing with sworn statements and the latter typically applies to documents that must be signed in front of an unbiased independent witness aka the notary.
A normal ECG is illustrated above. Note that the heart is beating in a regular sinus rhythm between 60 - 100 beats per minute (specifically 82 bpm).All the important intervals on this recording are within normal ranges. 1. P wave: 1  upright in leads I, aVF and V3 - V6.. QRS complex: 1  Duration less than or equal to 0.12 seconds, amplitude greater than 0.5 mV in at least one standard lead, and greater than 1.0 mV in at least one precordial lead. 2  Upper limit of normal amplitude is 2.5 - 3.0 mV.
Each year millions of people experience abnormal heart rhythms (arrhythmias), which are common as we age. For most, a normal resting heart rate is 60 to 100 beats per minute (bpm). For athletic individuals, a normal resting heart rate may be as low as 40 to 60 bpm.Abnormal heart rhythms can be described as a heart beating too fast (above 100 bpm) or slow (below 60 bpm), a fluttering sensation in the chest area or the skipping of a heart beat.or athletic individuals, a normal resting heart rate may be as low as 40 to 60 bpm.
