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.
In newborn infants up to one year old, 100 to 160 bpm is normal. Children between one and 10 years old range from 70 to 120 bpm. After the age of 10, up to adults and seniors, 60 to 100 bpm are considered normal, often centered on 72 as a benchmark for healthy, resting adults.hysiologists at Montana State University report resting heart rates of 28 to 40 bpm. More common rates for most athletes range between the low 40s and low 50s. Normal athletic heart rates are low because athletes' heart muscles are so strong, a single beat pumps more than a normal amount of blood.
