Omron monitor diagnoses arrhythmia in myasthenia patients

Supplier: Omron
02 September, 2011

Patient: Male, 65 years old Major compliant: Palpitation and tachycardia Medical history: Serious myasthenia gravis (thymus extirpation -1996), Angina (AC bypass operation-1996).

This patient has been visited at home once every two weeks since 1998 to manage his serious myasthenia. This patient complained of discomfort of the left anterior chest and a rapid pulse.

He said the symptoms happened infrequently, so we decided to lease HOG-801 to record ECG as symptoms occur, thinking it may be difficult to record his symptoms by 12-lead ECG nor a Holter monitor.

Monitor Outcome

The patient was trained to record his own ECG as symptoms occurred. Two weeks later, the patient brought in six sets of ECG data. Two of them showed PVCs (Figure 1); one was the fast heart beat suspected of being slight tachycardia

(Figure 2); and 3 sets of data were sinus rhythm. Premature heartbeats occurred 10 times a minute, but the physicians concluded treatment wasn’t necessary for this arrhythmia because the premature heartbeats happened alone and not in conjunction with a rapid heartbeat.

This patient worried of the reoccurrence of angina from his symptoms, so he was relieved very much when we explained his symptom was from arrhythmia (which does not need speci?c treatment ), not from the reoccurrence of angina. He fully understood the result of the diagnosis because ECG data corresponded with the palpitation and fast heartbeat which he could actually feel.

Physicians‘ Comments

It is dif?cult for patients with serious abnormal muscle weakness to visit a doctor’s of?ce. So it is also dif?cult to use a Holter monitor for these patients because a doctor or a nurse must visit them two clays in a row to attach and remove the Holter monitor.

In this situation, a medical examination using a conventional 12-lead ECG or a Holter monitor sometimes can not record ECG of the home-care patients who complain of chest pains when the symptoms occur.

So early and proper treatment is dif?cult and it might cause a decrease in a patient's quality of life. We con?rmed that the HCG-801 was able to be used by the patient who had serious muscle weakness or fatigue, so we assume that the HCG-801 can be used widely by elderly people who have dif?culties in activities of daily living but can record their ECG when symptoms occur.

From this experience, we conclude that a patient’s con?dence and satisfaction in the doctor‘s diagnosis could increase dramatically if ECG results during symptoms are explained well to the patients.

Therefore, we think medical examination with the portable ECG monitor can complement conventional 12-lead ECG and Holter monitors because it accurately records ECG when symptoms occur.

To demonstrate the ef?cacy of the HCG-801, we would like to conduct a clinical study to use HCG-801 for group examination among about 50 people who have had a comprehensive medical checkup and complain of chest pain.
