Appendix
General Knowledge of ECG
Normal sinus rhythm: In sinus conditions, S
heart rate is in the range of 60 to 100 times
per minute and the rhythm is regular. P wave is
normal and each one is followed by a QRS wave.
P-R interval: 0.12~0.20s;
QRS wave: 0.06~0.10s; No ectopic ECG activity.
Symptom: Sinus rhythm, heart rate: 60~100bpm
Indication: Normal
Several abnormal ECG waveforms
1) Tachycardia: The heartbeat becomes faster.
Tachycardia is determined by the rhythm of the
heart, the average rhythm beats faster than 100
times a minute is considered as Tachycardia. The
result description "Suspected fast beat" in this
device may be doubted as Tachycardia.
Symptom: heart rate>100bpm
Indication: It may occur with the normal people
who have these physiology
conditions: rage, fatigue, smoking, drinking too
much wine, excessive coffee and strong tea, etc.
Pathology: anemia, Hyperthyroidism, blood hypoxia, myocarditis, hypokalemia, fever, influence of some medication
(such as atropine, epinephrine etc.).
Suggestion: If it belongs to pathology condition, please go to hospital.
2) Bradycardia: The heartbeat becomes more
slowly. It is determined by the rhythm of the heart,
the average rhythm is less than 60 beats per
minute is considered as Bradycardia. The result
description "Suspected slow beat" in this device
may be doubted as Bradycardia.
Symptom: heart rate<60bpm
Indication: It occurs when healthy people fall
asleep, and it can be found in athlete (or those
who love doing sports frequently), old people,
or vagus excitement person.
Pathology: Sick sinus syndrome, Ischemic heart disease,Cardiomyopathy, intracranial hypertension, increased hypokalemia,
Low temperature, period of convalescence of acute infectious disease or after use some medicines such as digitalis.
Suggestion: If it belongs to the pathology condition, please see the doctor.
3) Premature beat: In a normal beat a QRS waveform appears prematurely and is followed by a comeback pause. The result
description "Suspected occasional short beat interval" in this device may be doubted as Premature beat.
What is premature beats?It is premature contraction. The normal heart beat is always regularly, and each beat interval
is also symmetrically; Premature beat is out of his general regulation, the heart beats prematurely and followed by a
long time interval; the phenomena of a premature beat between two heart beats is called inserting premature beat. The
display of "early beat" may be suspected Premature beat.
According to different original positions it can be divided into Premature Atrial Contraction,
