Cardiac Monitoring


HSMD is a provider of mobile medical testing to physicians and Healthcare facilities. HSMD provides physicians the ability to offer in house excellent testing services without the capital investment.


Monitoring Services:



Mobile Cardiac Telemetry (MCT) is the latest technology in ambulatory cardiac monitoring. Like an event monitor, MCT is useful to diagnose arrhythmias that only occur once in awhile. It is a small, portable heart monitoring system that can automatically capture and transmit heartís abnormal electric activity to a cardiac monitoring center, even if patient does not have symptoms.



Event monitors are useful to diagnose arrhythmias that only occur once in awhile. The small, portable device is worn continuously for multiple days, and it records the heart's electrical activity when patients push a button on the device indicating their symptoms.



This small, portable device records the heart's electrical activity continuously over a 24 to 48 hour period.



Ambulatory sleep monitor allows physicians to determine if a patient have sleep apnea This low cost screening can save patients cost and inconvenience in full onsite sleep study.


Indications for cardiac monitoring

  • Palpitations, fast or racing heartbeat, a slow heartbeat, or an irregular heartbeat
  • Weakness, chronic fatigue
  • Shortness of breath
  • Chest pain
  • Syncope, fainting
  • Dizziness, lightheadedness
  • Non-life threatening arrhythmias such as supraventricular tachycardias (e.g. atrial fibrillation, atrial flutter, PACs, PSVT) and ventricular ectopy
  • Bradyarrhythmias and complete, partial or intermittent bundle branch block
  • Stroke, TIA or other embolic events workup
  • Follow up after myocardial infarction, cardioversion, cardiac surgery
  • Follow up after cardiac arrhythmia ablation
  • Patient with sleep apnea
  • Patients who require monitoring of effect of certain medications known to affect cardiac rhythm


Cardiac Monitors

  • Each cardiac monitor is small, lightweight, and simple to hook up and operate
  • Patients can always reach our trained cardiac technician 24/7 to answer any questions
  • Patients transmit baseline and symptoms related event strips at any time
  • Event strips are reviewed by certified cardiac technicians and then immediately reported and posted on our secure online portal
  • At the end of the study HSMD will provide a summary report showing the most important rhythm strips



Our highly trained cardiac technicians monitors your patient heart rhythm, notified the physician with any concerning reading, call patient to make sure your patient is doing OK and give them advice based on each doctor protocol.


Patient help line

Our cardiac technicians await your patient calls 24-hours a day 7 days a week to answer their questions and help them with any of their monitor issues.


Complete Service to your facility

HSMD provides all of the equipments, supplies, monitoring, interpretation, customer service and reports that you need to offer cardiac monitoring for your patients without the purchase of medical equipments or softwares while increasing quality of services and revenues.

"The Diagnosis of Cardiac Arrhythmias: A Prospective Multi-Center Randomized Study Comparing Mobile Cardiac Outpatient Telemetry versus Standard Loop Event Monitoring"




Ambulatory electrocardiographic monitoring systems are frequently used in the outpatient evaluation of symptoms suggestive of a cardiac arrhythmia; however, they have a low yield in the identification of clinically significant but infrequent, brief, and/or intermittently symptomatic arrhythmias. The purpose of this study was to compare the relative value of a mobile cardiac outpatient telemetry system (MCOT) with a patient-activated external looping event monitor (LOOP) for symptoms thought to be due to an arrhythmia.



The study was a 17-center prospective clinical trial with patients randomized to either LOOP or MCOT for up to 30 days. Subjects with symptoms of syncope, presyncope, or severe palpitations who had a nondiagnostic 24-hour Holter monitor were randomized. The primary endpoint was the confirmation or exclusion of a probable arrhythmic cause of their symptoms. A total of 266 patients who completed the monitoring period were analyzed. A diagnosis was made in 88% of MCOT subjects compared with 75% of LOOP subjects (P = 0.008). In a subgroup of patients presenting with syncope or presyncope, a diagnosis was made in 89% of MCOT subjects versus 69% of LOOP subjects (P = 0.008). MCOT was superior in confirming the diagnosis of clinical significant arrhythmias, detecting such events in 55 of 134 patients (41%) compared with 19 of 132 patients (15%) in the LOOP group (P < 0.001).



MCOT provided a significantly higher yield than standard cardiac loop recorders in patients with symptoms suggestive of a significant cardiac arrhythmia.


Staff/patient information:

Preparing the Skin & Applying the Patches

Good skin preparation means better ECG signal traces that in turn are easier for the doctor to review and evaluate.

Advise the patient to change their electrodes every two days.

When re-applied, change their location slightly to prevent skin irritation.

If the patient complains of skin irritation, ask them to call HSMD, Alternative Patches may be available to reduce irritation.


  1. Choose areas of the chest that are flat and not very muscular. Avoid skin folds or creases, irritated skin or scars.
  2. Shave areas with hair using the skin patch (electrode) as a guide for the size of the area to shave. This insures good contact and makes electrode removal easier.
  3. Wash each site well with PLAIN soap and water. (You should not use soap that contains lotion or oil.) Dry thoroughly.
  4. Snap the wires onto the electrodes while they are still attached to the strip of plastic backing.
  5. One by one, peel each electrode from the backing and apply it to the chest, using the placement in the illustrations.
