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.
1 Normal range up to 120 ms (3 small squares on ECG paper). 2  QT interval (measured from first deflection of QRS complex to end of T wave at isoelectric line). 3  Normal range up to 440 ms (though varies with heart rate and may be slightly longer in females).he amplitude, or voltage, of the recorded electrical signal is expressed on an ECG in the vertical dimension and is measured in millivolts (mV). On standard ECG paper 1mV is represented by a deflection of 10 mm.
