Patient assessment tool is the equipment used to treat patients either outdoors or inside the hospital or any medical center. An electrocardiogram (ECG) is a simple diagnostic test to detect the heartbeat by placing some electrodes on our body. The ECG monitor also provides all the problems related to the heart and heart functioning. An ECG monitor is a simple, non-invasive, painless test that can be performed in virtually any clinic, doctor's office or medical facility. From the ECG monitor it is possible to determine whether our rhythm is normal or abnormal. Abnormal rhythm includes slow rhythms (cardiac Brady), fast rhythms (tachycardia), and heart block. Additionally, the ECG monitor can show the effects of electrolytes (normal or abnormal blood tests) and medications on the heart. (Cohen 2010) A doctor may recommend an ECG monitor to patients because of their symptoms or who may be at risk for heart disease because there may be a family history of heart disease or smoking, being overweight, having diabetes, high cholesterol, or high blood pressure. (Better Health 2013). Some health problems diagnosed by ECG monitor are heart shape, heart functioning, blood supply to the heart, heart positioning, cardiac arrest, electrolyte balance in the heart, blood artery control, irregular and abnormal heart beats. (Royal Melbourne Hospital - Department of Cardiology) ECG is performed by attaching 12 ECG electrodes to patients. It will print a copy of the rhythm strip. After completion, a paramedic or ECG technician normally performs this simple, painless investigation by placing electrodes in the patient's chest, wrist and ankles. This records the electrical activity of...... middle of paper ......th of patients diagnosed with a heart problem, to help evaluate the artificial heart pacemaker or to monitor certain drugs in the heart. (Royal Melbourne Hospital - Department of Cardiology page 3). The 3 main types of ECG are: -. 1) Resting ECG:- The patient lies down and no movement is allowed during this period, here the impulse generated by our muscles can interfere with the impulse generated by our heart. This method can take five to ten minutes. 2) Ambulatory ECG: This ECG is recorded by a portable recording device that is worn for at least 24 hours. Patients can move freely when the monitor is mounted on the body. The patient's recovery from heart disease will undergo this type of ECG. 3) Cardiac arrest test: This type of ECG is performed for a patient ride on the exercise bike or a walk in a mill which takes 15-20 minutes to complete.
