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 co󰀨ee and strong tea, etc.
Pathology: anemia, Hyperthyroidism, blood hypoxia, myocarditis, hypokalemia, fever, inuence 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.
ENGLISH

28
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 di󰀨erent original positions it can be divided into Premature Atrial Contraction,
Premature Nodal Contraction and Premature Ventricular Contraction (PVC), which needed to be judged by experts.
Symptom: The heart beat is arrhythmic, it occurs as the phenomenon that the heart suddenly beats and then stops for
a while. Some people have palpitation or have no symptom.
Indication: The premature beat can be found occasionally in healthy people, with no distinct symptom or sometimes
with palpitation. This may be caused by fatigue,
anxiety, insomnia, smoking too much, or drinking too much wine, co󰀨ee, strong tea etc. It can be recovered without
treatment. However, if premature beat occurs frequently, continuously or in multi-focus, it will indicate functional
cardiovascular disease. please see a doctor as soon as possible.
Suggestion: The character of premature beat needs professional to conrm, so please save the temporal gure in time.
When seeing a doctor , you can recall it to doctor to judge the character of premature(Premature Atrial Contraction,
Premature Nodal Contraction, Premature Ventricular Contraction or multi-focus premature beat and help cure.
Testee’s Symptom: Normal heart beat is followed by a premature beat.
4) Bigeminy: It is a type of PVC in which a normal beat is coupled
with a premature beat.
Indication: PVC occurs frequently.
Suggestion: Please see the doctor.
5) Trigeminy: It is a type of PVC in which two normal beats are coupled
with a premature beat.
Indication: PVC occurs frequently.
Suggestion: Please see the doctor.
The result description “Suspected irregular beat interval” in this device
may be doubted as Bigeminy or Trigeminy.
6) Short run of tachycardia: PVC (Premature Ventricular Contraction)
occurs more than 3 times continuously.
Testee’s Symptom: PVC occurs More than 3 times continuously. The
heart beat is fast and regularly, but starts and stops suddenly.
According to the di󰀨erent of active original position, it can be divided
into:Short Run, SVE Short Run (Needing professional to judge).
Short Run:It is caused by Premature Atrial Contraction or Nodal
Premature Beat, frequency>180bpm.
Indication:Most commonly found in healthy people, it causes by deep respiration, tachypnea, positional changes, swallow,
rage etc. It also appears in functional cardiac disease,such as Wol󰀨 - Parkinson-White Syndrome, rheumatic heart
disease, coronary heart disease, Cardiomyopathy, Congenital heart disease, medicinal reaction(digitalis toxicosis)etc.
Suggestion:If it occurs time after time, please see the doctor as soon as possible.
Ventricular Tachycardia:Caused by Premature Ventricular Contraction, Heart Rate >140bpm.
Indication:Most commonly found in heart disease patient, it can cause ventricle brillation if it’s serious, so the tester
needs to see a doctor immediately.
Suggestion:The character of short run needs professional to conrm, so please save the temporal gure in time. And
