Top vendors for Cardiac Monitors, compared

A plain-English breakdown of six vendors in and around the cardiac monitoring space — who makes actual monitors, who supports the ecosystem, and who does something else entirely.

TL;DR

This list covers a range of companies at different points in the cardiac monitoring ecosystem. Three of them are directly in the space: TZ MEDICAL, INC. is a hardware manufacturer with 30+ years of history and a current GSA contract. AirStrip Technologies, Inc. is a software platform that aggregates data from monitors you already own. Wearlinq makes the eWave, a FDA-cleared wearable 6-lead wireless monitor, and backs it with an in-house IDTF interpretation service.

ELECTRO MEDICAL EQUIPMENT CO., INC. is adjacent — they manufacture telemetry pouches, ECG paper, and electrodes, not monitors themselves. The remaining two vendors don't belong in a cardiac monitor evaluation: Turing Medical develops neuromodulation therapy for depression and chronic pain, while Axon Therapies, Inc. is a clinical-stage company building an ablation catheter for heart failure with preserved ejection fraction (HFpEF). Both are worth knowing about for clinical program planning, but neither makes a cardiac monitor.

How they compare

Hardware, software, and wearables

TZ MEDICAL, INC. manufactures complete cardiac monitoring systems under the TZ Monitoring Solutions brand, alongside radial access and interventional cardiology accessories. They hold a current VA/GSA Federal Supply Schedule contract (Contract #36F79723D0080, valid through July 2028), which gives government and government-affiliated facilities a straightforward procurement path. One publicly verifiable price point: the V1-MPC Patient Companion Multi-Port Connect is listed on that GSA schedule at $13,701.12. Manufacturing runs across multiple US locations. For facilities that want a single hardware-focused manufacturer with a federal contract already in place, TZ Medical is the most structurally simple option in this group.

AirStrip Technologies, Inc. doesn't make a monitor — they make a layer that sits on top of your existing monitors. Their platform pulls real-time waveforms from bedside monitors, EMRs, and connected devices, and displays up to 40 patients per screen across ICU, Emergency, Cardiology, and Rapid Response units. Critically, it supports diagnostic-quality 12-lead ECG capture with automated STEMI notifications. The vendor-agnostic design means it doesn't require ripping out your current fleet. If you're managing a multi-vendor monitor environment or have care coordination gaps between units, that interoperability is the core value.

Wearlinq targets ambulatory and extended monitoring. Their eWave device delivers 6-lead wireless ECG with skin-like electrodes and a 5-day battery life per charge — no trailing wires, continuous cloud transmission. It's FDA-cleared for mobile cardiac telemetry and extended Holter monitoring. What sets Wearlinq apart from a pure device play is that they also operate an in-house IDTF (Independent Diagnostic Testing Facility), reporting 33 years of cardiology service experience, staffed by Certified Cardiac Technicians. That means the ordering clinic doesn't need to manage interpretation staffing in-house. Outpatient cardiology practices and clinics without a dedicated cardiac technician on staff should pay attention to that end-to-end structure.

Consumables that keep telemetry programs running

Running a telemetry floor burns through a high volume of pouches, ECG paper, and electrodes. ELECTRO MEDICAL EQUIPMENT CO., INC. has manufactured those consumables since 1976 out of Louisiana. They're veteran-owned, US-manufactured, and their cardiac line covers diagnostic ECG paper, cardiology electrodes, and telemetry pouches in multiple configurations. Pricing is not publicly listed — you'll need a direct quote. But for a bulk consumables contract, their longevity and domestic manufacturing are meaningful factors, especially for supply-chain-sensitive procurement teams.

A note on vendors outside this category

Turing Medical develops the PACE platform, a precision-guided cortical stimulation therapy for severe depression and chronic pain. It has nothing to do with cardiac monitoring. Axon Therapies, Inc. is building the Satera Ablation System, which targets the greater splanchnic nerve to treat HFpEF — a therapeutic intervention, not a monitoring device, and not yet commercially available. Neither vendor belongs in a cardiac monitor RFP. Axon Therapies may be relevant to cardiac program directors tracking emerging HFpEF treatment pipelines, but that's a separate procurement conversation.

How to choose

Match the gap you're actually filling to the right vendor type:

• If you need hardware cardiac monitoring with an existing federal procurement vehicle, TZ MEDICAL, INC. is GSA-listed and domestically manufactured — straightforward for VA, DoD, or government-affiliated facilities.
• If you're operating a multi-vendor monitor environment and need unified surveillance or alarm management, AirStrip Technologies, Inc. integrates across your existing fleet rather than replacing it.
• If you're building or expanding an ambulatory or outpatient cardiac monitoring program, Wearlinq's eWave plus its IDTF interpretation service is a compact end-to-end option — especially if your clinic lacks in-house ECG analysis staff.
• If you need recurring consumables — telemetry pouches, ECG paper, electrodes — to
