Lab 2.1 ECG Calculations

3.2.1 ECG Calculations. After performing experiments with the help of doctors and cooperation of a subject a certain reading is to taken.[42-51] All the obtained reading are compared with the normal reading of a subjects and some references i.e Dr.Bllams and Dr.Johnsons quotsons. The ECG abnormalities are detected by measuring and comparing P-R, QRS and Q-T intervals with normal values. Below the table is a normal reading of a human. Variations of these readings represent variations in ECG. It is well known that the electrical conduction through the heart follows a certain pathway under normal conditions. When a disturbances in these pathways will alter the pathway of the wave of depolarization must follow and change the timing of the electrical events.
Table -3.1: Normal Range Of ECG.
Types of interval Duration
P-R interval 0.12-0.2 seconds
QRS interval Up to <0.1seconds
Q-T interval
Hot: After performing experiment over subjects the variations of Temperature i.e. Hot as given below:
a) 41 °C (105.8 °F) – (Medical emergency) – Fainting, vomiting, severe headache, dizziness, confusion, hallucinations, delirium and drowsiness can occur. There may also be palpitations and breathlessness.
b) 40 °C (104.0 °F) – Fainting, dehydration, weakness, vomiting, headache, breathlessness and dizziness may occur as well as profuse sweating. Starts to be life-threatening.
c) 39 °C (102.2 °F) – Severe sweating, flushed and red. Fast heart rate and breathlessness. There may be exhaustion accompanying this. Children and people with epilepsy may be very likely to get convulsions at this point.
d) 38 °C (100.4 °F) – (this is classed as hyperthermia if not caused by a fever) Feeling hot, sweating, feeling thirsty, feeling very uncomfortable, slightly hungry. If this is caused by fever, there may also be chills.
Cold : After performing experiment over subjects the variations of Temperature i.e. cold as given
