Phillip Zmijewski's Guide to Cardiac Telemetry: What Patients and Families Should Know About the People Watching the Monitors

With years of frontline experience in hospital monitoring, Phillip M. Zmijewski breaks down what telemetry actually is, how monitor techs work, and what families on a cardiac floor should understand about the team behind the screens.

Cardiac telemetry is one of the most common forms of patient monitoring in American hospitals, yet most patients and families have only the vaguest sense of how it actually works. The leads get placed on the chest, a small transmitter is clipped to the gown, and somewhere out of sight a team of monitor technicians watches the rhythm in real time.

For Phillip M. Zmijewski, a Florida-based healthcare and maritime professional with hands-on monitoring experience, the gap between what patients see and what actually happens behind the scenes is worth closing.

“People assume telemetry is automatic, like a smoke detector. It is not. There is a person on the other end of that signal, and the quality of that person’s training and attention has a direct effect on patient outcomes.”

Phillip’s Pre-Shift Checklist: What Monitor Techs Actually Do

Telemetry monitoring looks passive from the outside, but the work is structured and demanding. Phillip walks through the routine he relied on at the start of every shift.

Lead placement and signal quality. Before anything else, the tech confirms each patient’s leads are reading clean. A poor signal generates false alarms and hides real ones.
Baseline rhythm review. The tech reviews each patient’s baseline EKG and any prior strips so abnormal events stand out against the patient’s normal pattern.
Alarm parameter check. Heart rate limits and arrhythmia settings are reviewed against the physician’s orders, since defaults are rarely right for every patient.
Communication with bedside nurses. The tech introduces themselves to the floor team and confirms how escalations should be handled for the shift.

What ‘EKG Tech’ Actually Means

According to the American Heart Association, more than six million patients are placed on cardiac telemetry every year in the United States. The roles supporting that work go by several names, and Phillip is the first to point out that the labels matter.

“Calling everyone an EKG tech is imprecise. The person running a 12-lead in an outpatient clinic, the technician handling stress tests, and the monitor tech watching a telemetry bank are doing different jobs. Lumping them together hurts the workforce and confuses patients.”

Phillip recommends that patients and families ask which type of cardiac monitoring their loved one is on, and who is responsible for watching it. The answers vary widely from one hospital to the next.

Where AI Fits In

Artificial intelligence is being added to monitoring systems across the country, with algorithms designed to flag rhythm changes earlier and reduce alarm volume. Phillip considers the technology useful but warns against treating it as a replacement for trained human attention.

AI is good at suppressing obvious artifact and reducing alarm fatigue.
AI still produces false positives that require a trained reviewer.
AI cannot replace the clinical context an experienced tech brings to a shift.
The best results come from AI as a second set of eyes, not a cost-cutting tool.

What Patients and Families Can Ask

Phillip suggests that anyone admitted to a telemetry unit, or visiting someone who is, can quietly ask a few questions that improve communication with the care team.

Is the patient on continuous cardiac monitoring, and if so, what type?
Who reviews the rhythm and how quickly are abnormal events escalated?
Are alarm parameters individualized for the patient’s baseline?
Who should the family contact if they notice the leads have come loose?

A Final Word From Phillip

For Phillip M. Zmijewski, the goal of talking openly about telemetry is not to alarm patients but to give them a better understanding of the team protecting them.

“The monitor tech is one of the quiet roles in a hospital, and most patients never meet them. But that screen is being watched by a real person making real decisions, and patients should know that. Asking a few simple questions makes the whole system work better for everyone.”
