An EKG machine looks like a simple purchase until you compare listings. Two 12-lead units at very different prices can record the same tracing, yet one prints an interpretation, sends results to your EHR and runs all day on battery, while the other only prints. This page is a Texas buyer's map of the EKG/ECG market: the questions that narrow the choice, the model families you will see most often, what actually moves the price, and what a refurbished unit should come with.
Mr. Biomed Tech Services sells new and refurbished EKG machines alongside our other medical equipment for sale in Texas, and our CBET-certified engineers test each unit from our Garland headquarters before it ships.

EKG or ECG: same machine, same test
EKG and ECG are two abbreviations for the electrocardiogram. "EKG" comes from the German spelling and is common in U.S. clinics; "ECG" is the international term. Listings use both for the same resting 12-lead machine, so search under both names when you compare prices. In the U.S., electrocardiographs are regulated by the FDA as Class II medical devices under 21 CFR 870.2340, which is one reason a reputable seller should be able to tell you the manufacturer, model and software version of any unit it offers.
Three questions that narrow the choice
- Do you need an interpretation statement? Interpretive machines print a computer-generated reading (for example, sinus rhythm or a possible infarct pattern) with the tracing. Primary care, urgent care and occupational health clinics usually want it; a cardiology practice may over-read every tracing anyway. Interpretation is often a licensed software option, so confirm it is enabled on the exact unit you buy.
- Where does the tracing need to go? If results must reach an EHR or a cardiology management system, check the export options first: network or Wi-Fi connectivity, DICOM or XML output, PDF export, or a USB transfer. A machine that only prints may cost less but create scanning work every day.
- Will it stay on a cart or travel? A cart-mounted unit with a full-size printer suits a single exam room or a hospital floor. Compact handheld or tablet-style units suit mobile occupational health, home visits and small offices, but often have smaller screens and printers.
Model families buyers compare most
These are the EKG families that appear most often on the new and refurbished market in Texas. Availability changes month to month, so treat this as a guide to what to ask about rather than a stock list.
| Family | Typical setting | What to check on a listing |
|---|---|---|
| GE MAC series (for example MAC 2000, MAC 5500 HD) | Clinics through hospital cardiology | Interpretation option, connectivity option, software version, printer condition |
| Philips PageWriter TC series (TC20, TC35, TC50, TC70) | Clinics, emergency departments, inpatient units | Interpretation and network licenses, touchscreen condition, battery age |
| Welch Allyn ELI series, formerly Mortara (ELI 150c, 250c, 280) | Primary care, occupational health, hospitals | Interpretation option, keyboard and screen wear, export options |
| Schiller Cardiovit and compact handheld units | Small offices, mobile and screening work | Printer width, data export, availability of cables and parts |

What moves the price
- Software options. Interpretation, pediatric criteria, connectivity and storage are frequently separate licenses. Two units with the same model name can differ by several options.
- Generation and support status. Newer generations cost more, but they usually have current parts and software support. Older units can be good value if cables, batteries and printer parts are still available.
- Condition of the wear parts. Batteries, printer mechanisms, keyboards and touchscreens wear first. A unit with a new battery and a tested printer is worth more than one with the originals.
- Accessories included. A patient cable, a full set of lead wires, a cart and a power supply can add up quickly if they are missing.
- New or refurbished. New units come with the manufacturer's warranty and the latest software. Refurbished units cost less and, from us, come with a 90-day warranty on reconditioned equipment.
What a refurbished EKG should come with
Before you accept a refurbished EKG machine, ask for a written test record showing a simulator check of all 12 leads, standard calibration (10 mm/mV at 25 mm/s), an electrical safety test, the software version and enabled options, and the battery and printer condition. You should also receive a list of included accessories and the warranty terms. Our Dallas EKG inspection walkthrough explains each of these checks in plain language.
Buying in Dallas–Fort Worth or elsewhere in Texas
Across Dallas–Fort Worth, we can usually deliver and set up an in-stock machine the same day, and you are welcome to see a unit at our Garland headquarters by appointment. If you are still deciding which features your practice needs, our ECG feature guide by practice type compares options for cardiology, primary care, urgent care and occupational health. Elsewhere within about 300 miles of Garland, we confirm the delivery date when you order.
After the sale: keeping it accurate
Most EKG problems after purchase are not the machine at all but lead wires, electrode prep or filter settings. Our EKG machine repair and calibration guide helps staff tell a cable fault from a machine fault, and our engineers respond to service requests in under 8 business hours, Monday through Friday, with same-day on-site service across Dallas–Fort Worth.
To ask about current EKG stock, call (469) 767-8853 or send us a request with the features you need.
