Heart Observer Instruction Manual114. ECG MeasurementImportant Notes on Taking a MeasurementIn order to obtain a good heart rate reading, it is important that measurements are taken correctly.Before taking a measurement for the first time, read these instructions carefully and make sure youobserve the following tips each time you take a measurement. Make sure that the electrodes are directly touching your skin. If your hands or skin are dry, wipe them with a damp towel so that they are slightly moist. If the electrodes are dirty, wipe any dirt off with a soft cloth moistened with disinfectant alcohol or acotton swab.----- Take care not to use too much disinfectant alcohol when cleaning the electrodes.----- Do not spray or apply disinfectant alcohol on parts other than the electrodes. Do not move during measurement.----- Movement, including talking, coughing, or sneezing, during measurement may affect themeasurement results. If the position of your finger or arm is inappropriate during measurement, the results may beunreliable, so make sure to check their position before taking a measurement.
Heart Observer Instruction Manual12 After taking a measurement, disinfect the electrodes by wiping them with a soft cloth or cotton swabmoistened with disinfectant alcohol. If you do not disinfect the electrodes there is a risk of skindisease.Measurement methodsPreparationMake sure that you are in relaxed position. And user can take a measurement as the followingmethods. Prepare your pose and then press the START button to start a measurement. Themeasuring mode is depended on your setting in“ECG measure”menu. Refer to“MeasurementMode settings”.NoteThe ideal posture is one where you are seated comfortably with your back straight. You can alsotake a measurement while you are standing or while lying down.Palm-palm measurementMake sure that hold the metal electrode 3 of the unit with the rightthumb and the electrode 1 with the right index fingerthen hold theelectrode 9 with left thumb and the electrode 10 with the left indexfinger, refer to Picture 4-1.Palm-chest measurement:Picture 4-1
Heart Observer Instruction Manual13If palm measurement is not ideal, please adopt palm-chest measurement. Hold the unit with right hand;make sure that the index finger touch metal electrode 1 and right thumb touch metal electrode 3comfortably and closely. Place the electrode 10 against left chest on bare skin about 5 cm bellow yourleft nipple. (Refer to picture 4-2 )Picture 4-2Note: If you have any problems applying the unit when measuring in palm-chest mode, please askyour doctor for advice.Improper Operation Methods:A. The touch point of the right hand does not contact well with the unit.B. The handheld gesture is NOT correct.
Heart Observer Instruction Manual14C. The electrode 10 does not contact fully the skin.(E.g. with clothes on body while takingmeasurements).Measurement for FemaleLocate the unit at the lower end of breastbone and move horizontallyto the middle of the left part of the chest. If necessary, gently lift the breastand place the “10” electrode under the left breast. Unless the electrodecomes in contact with the brassiere, it is NOT necessary to remove it;if you have any problem, please consult your doctor.Important: The small open circle indicates the proper position of electrodes, as shown in Picture 4-3.Notes: Make sure that you are relaxed and that your chest is free of tension. Press the electrode 10 to make it closely against your bare chest. Do not place the electrodeon clothing as this will result in an inaccurate measurement. If measuring in dry circumstance, which might cause weak heart pulse signal, please wetyour skin or hands with some diluted salt water or clean water. This would strengthen thePicture 4-3
Heart Observer Instruction Manual15heart pulse signals, and make the analysis much more accurate.When taking an palm-chest measurement, if you have problems applying the unit so that themetal electrodes 10 is flat against your chest, please ask your doctor for advice.Measurement Mode settingsSelect “Ecg Measure” item, shown in picture 4-4, and thenShort press the POWER button to enter the screen such asin pic.4-5(1).There are two measurement modes for selection, such as Easyand Continue, refer to pic.4-5(1) and pic.4-5(2).Press the LEFT or RIGHT button to move the selection box.Then short press the POWER button and the little black quadrate macula shifts to below the itemand indicates the item is selected.

Heart Observer Instruction Manual37AppendixGeneral information about the Heart Rate MeasurementsThe heart is a muscular pump controlled by electrical impulses generated by the body. It is dividedinto two by the septa and each side has two chambers –an atrium and a ventricle-linked by aone-way valve. The left atrium and ventricle control oxygenated blood, and the right atrium andventricle control de-oxygenated (“used”) blood.The electrical impulse that causes the heart to beat spreads across the atria, causing the left andright atrium to contract and pump blood into the left and right ventricles respectively. The towventricles then contract and pump blood out of the heart. The heart muscle then relaxes, orre-polarises, allowing blood to fill up the heart again.
Heart Observer Instruction Manual38An Heart Observer is able to measure the electrical impulse as it passes across and through theheart, causing the heart to beat. An ECG does not measure the movement of your heartbeat, butrather the electrical activity that causes the heart to beat. The measurements recorded by an HeartObserver, when combined with a medical examination, can help your doctor monitor your heartcondition. The ECG measurements recorded by the unit are NOT designed or intended for medicaldiagnosis. Conditions such as arrhythmia and Ischemia can only be diagnosed by a doctor througha special examination.About the ECGThe ECG waveform shows the rhythm of your heartbeat during the 30-second measurement anddisplays the electrical activity causing the heart to beat. The waveform for each heartbeat showsthe progress of the electrical impulse across and through the heart.Ventricular contraction(QRS complex)Re-polarization (T wave)Atrial contraction (P wave)
Heart Observer Instruction Manual39The first peak indicates the spread of the impulse over the atria and the beginning of theircontraction. This is known as the P wave. The second peak indicates the spread of impulse overthe ventricles and the beginning of their contraction. This is known as the QRS complex. The thirdpeak indicates the activity as the heart relaxes (re-polarization), and is known as the T wave.What is Arrhythmia?Arrhythmia is a condition where the heartbeat rhythm is abnormal due to flaws in the bio-electricalsystem that drives the heartbeat. Typical symptoms are skipped heartbeats, premature contraction,an abnormally rapid (tachycardia) or slow (bradycardia) pulse. This can be caused by heart disease,ageing, physical predisposition, stress, lack of sleep, fatigue etc. Arrhythmia can only be diagnosedby a doctor through a special examination.What is Ischemia?Ischemia is a condition in which insufficient oxygen is supplied to parts of the heart or other parts ofthe body. This is usually due to a blockage or partial blockage of an artery.Ischemia can only be diagnosed by a doctor through a special examination.
