User Manual for Easy ECG Monitor3 Operation3.1 CautionsIn order to get a more credible measuring result, youshould pay attention to the following advice Do NOT engage in vigorous exercise prior totesting. Keep you relax while testing. Do NOT move and talk, try to keep as still aspossible during testing.3.2 Start to measure ECG(1) Press the (Power/Back) button (Lasting for 2seconds) to turn on the device.After boot-strap, the device starts to initialize, anddisplays the following pictures.(1)7
User Manual for Easy ECG Monitor(2)(3)(2) After initialization, the device will enter into apreparing phase; this phase will last 6 seconds (seethe following figure), during this period the devicewill judge whether the placed position is befitting.Please adjust your hand-hold position to obtain goodECG signal if the detected waveform is not smooth.8
User Manual for Easy ECG Monitor(3) During the preparing phase, the user can use 4methods to measure ECG: Measure through both hands, name as palmmeasurement. Measure through right hand and chest, name as chestmeasurement. Measure through right hand and left leg, name as legmeasurement. Measure through ECG lead wire, name as lead wiremeasurement.Note: when you use one of methods to measure, if youcan’t obtain enough intensity of ECG signal to analyze,please try to use another measuring method.9
User Manual for Easy ECG MonitorI Palm measurementHold the device with right hand. Make sure that the palmand fingers touch the metal electrode I and II reliably.Press the electrode III close against the center of the leftpalm. The ECG signal detected by Palm measurement isequivalent to Lead I ECG signal.Improper operating method:A.Waving your both hands at will.B.Both hands loose contact with electrodes duringmeasurement.C.Not palm contacts the electrode.10
User Manual for Easy ECG MonitorII Chest measurementIf palm measurement is not ideal, please adopt chestmeasurement. Hold the device with the right hand. Makesure that the palm and fingers touch the metal electrode Iand II reliably. Place the electrode III on bare skin about5cm away below the left nipple. The ECG signaldetected by Chest measurement is similar to Lead VECG signal.Improper operating methodA. The contact place of electrode III deviates from leftchest.B. The holding gesture is incorrect.C. The electrode can not contact bare skin completely.(For example place the electrode on clothing.)11
User Manual for Easy ECG MonitorIII Leg measurementIf palm measurement is not ideal and it is not convenientto use chest measurement, the leg measurement isrecommended. When measuring, hold the device withthe right hand. Make sure that the palm and fingerstouch the metal electrode I and II reliably. Place theelectrode III on the skin 10cm away above the left footankle. The ECG signal detected by Leg measurement isequivalent to Lead II ECG signal.Improper operating method:A. You moved your foot.B. Wrong holding gesture.C. The electrode III can not contact bare skin completely.(For example, place the electrode III on the sleeve oftrousers or socks.)12
User Manual for Easy ECG MonitorIV Lead wire measurementFor the sake of obtaining high quality ECG, lead wiremeasurement can be used. Connect the lead and thedevice effectively by lead wire socket. Place theelectrodes and connect the lead wires as the figure belowto obtain the Lead II ECG signal; if you want to measureLead I and Lead III ECG signal, please connect the leadwires to the electrodes according to the following table.Improper operating method:A.

User Manual for Easy ECG Monitor9 AppendixGeneral Knowledge of ECG1 Normal sinus rhythm: In sinus conditions, SA nodepaces the heart with the regularly rate and the normalrhythm. The heart rate is in the range of 60 to 100times per minute and the rhythm is regular. P wave isnormal and each one is followed by a QRS wave. P-Rinterval: 0.12 0.20s; QRS wave: 0.06 0.10s; Noectopic ECG activity. The display of “No apparentirregularity” may be regarded as Normal sinus rhythm.Symptom: Sinus rhythm, heart rate: 60 100bpmIndication: Normal2 Several abnormal ECG waveforms1) Tachycardia: The heartbeat becomes faster.According to the rhythm of the heart, the averagerhythm beats faster than 100 times a minute. Thedisplay of “fast beat” may be doubted as Tachycardia.Symptom: heart rate 100bpm45
User Manual for Easy ECG MonitorIndication: It may occur with the normal people whohave these physiology conditions: rage, fatigue,smoking, drinking too much wine, excessive coffeeand strong tea, etc.Pathology: anemia, Hyperthyroidism, blood hypoxia,myocarditis, hypokalemia, fever, influence of somemedication (such as atropine, epinephrine etc.).Suggestion: If it belongs to pathology condition,please go to hospital.2) Bradycardia: The heartbeat becomes more slowly.According to the rhythm of the heart, the averagerhythm is less than 60 beats per minute. The displayof “slow beat” may be suspected Bradycardia.Symptom: heart rate 60bpmIndication: It occurs when healthy people fall asleep,and it can be found in athlete (or those who lovedoing sports frequently), old people, or vagusexcitement person.Pathology: Sick sinus syndrome, Ischemic heartdisease,Cardiomyopathy, intracranial hypertension,increased hypokalemia, Low temperature, period ofconvalescence of acute infectious disease or after use46
User Manual for Easy ECG Monitorsome medicines such as digitalis.Suggestion:If it belongs to the pathology condition,please see a doctor.3) Premature beat:In a normal beat a QRS waveformappears prematurely and is followed by a comebackpause.What is premature beats？It is premature contraction.The normal heart beat is always regularly, and eachbeat interval is also symmetrically; Premature beat isout of this general regulation, the heart beatsprematurely and followed by a long time interval; thephenomena of a premature beat between two heartbeats is called inserting premature beat. The displayof “early beat” may be suspected Premature beat.According to different original positions，it can bedivided into：Premature atrial Contraction, PrematureNodal Contraction and Premature VentricularContraction (PVC), which needed to be judged byexperts.Symptom: The heart beat is arrhythmic, it occurs asthe phenomenon that the heart suddenly beats andthen stops for a while. Some people have palpitationor have no symptom.47
User Manual for Easy ECG MonitorIndication: The premature beat can be foundoccasionally in healthy people, with no distinctsymptom or sometimes with palpitation. This may becaused by fatigue, anxiety, insomnia, smoking toomuch, or drinking too much wine, coffee, strong teaetc. It can be recovered without treatment. However,if premature beat occurs frequently, continuously or inmulti-focus, it will indicate functional cardiovasculardisease. please see a doctor as soon as possible。Suggestion: The character of premature beat needsprofessional to confirm, so please save the temporalfigure in time. When seeing a doctor , you can recall itto doctor to judge the character of premature（ Premature Atrial Contraction, Premature NodalContraction, Premature Ventricular Contraction ormulti-focus premature beat）and help cure.Testee’s Symptom: Normal heart beat is fol
