Everyone wants to buy nice equipment, so you go for the highest sampling rate you can find. You do that because everyone knows that more data is always best.
What Sampling Rate Do I Need?
That depends entirely on what you want from your data. 250 – 500 Hz can work perfectly well in the clinic. 1000 Hz is better, and it’s what’s in use these days, generally. More than this won’t necessarily add information for the classical assessment methods.
Who needs an ECG machine?
Hospitals, clinics, cardiologists, doctors, and other healthcare professionals use ECG machines every day. The devices are indispensable for assessing heart rhythm, diagnosing poor blood flow to the heart and detecting heart abnormalities such as chamber enlargement. They also recognize abnormal electrical conduction and heart attack. Individuals with chronic heart problems may want to have an ECG machine available at home.
Which type of ECG machine is best for me?
ECG machines vary in size, shape, and functionality. Despite the differences, they all employ the same working principles. They monitor patient heart function and help to detect and diagnose abnormalities. Depending on your specific uses and application, they will vary in the type of data they’re able to record, output and monitor.
The four major parts of an ECG Machine
Electrodes are one of two types, bipolar or unipolar. The bipolar electrodes are placed on the wrists and the left leg to measure the voltage differential between the two. Unipolar electrodes measure the voltage differential between a reference electrode and the surface of the skin.
Connecting wires transmit the electrical signals collected by the electrodes and sends them to the amplifier. These lead wires connect directly to the electrodes. Then the signal is sent through them to the amplifier.
An amplifier reads the electrical signals generated by the heart and sends them to a buffer. The buffer stabilizes and translates the signal. The differential amplifier strengthens the signal by 100 times. The amplified signal allows for more accurate measurement.
The output device records onto graph paper and/or LCD screen the results of the electrocardiogram. Some EKG machines record the measurements into computers for analysis and interpretation.
ECG Software Interpretation
Reading an ECG report is complex, and an accurate interpretation requires a trained medical professional. Most ECG manufacturers offer software interpretation to assist medical professionals and to provide a software diagnosis of the ECG test. Software interpretation may also provide notice for possible errors during the ECG test. The interpretation report can be used as a second diagnostic opinion for medical professionals not thoroughly trained in reading ECG reports. Manufacturers use many different interpretation algorithms and they are continually improving. ECG interpretation programs have been in use for several decades and continually improve.
ECG Machine Accessories and Supplies
All ECG/EKG machines need supplies. Many need additional accessories to achieve optimum functionality. These include ECG Electrode, ECG Cables, Preb gels, ECG paper, ECG carts and many more. Your preferred ECG equipment vendor will be able to supply everything you need.
How to maintain ECG Machines
ECG machines should be regularly cleaned and maintained. A few simple steps will keep machines running well and lasting a long time.
After daily use, electrodes should be cleaned. If copper alloy electrodes become rusted, fine sandpaper will remove the rust after soaking overnight in a saline solution. Silver-plated electrodes can be gently wiped clean with water to avoid damaging the surface.
Lead wires can break or be easily damaged near connections. Avoid pulling or twisting with too much force. Check connections often.
Battery operated ECG machines should be charged daily.
Avoid heat, moisture, dust or shock. Store with a dust cover if possible.
Open the device every six months and remove dust with a can of compressed air. If used in high humidity environments, circuit boards can be dried with a household blow dryer set on low or no heat.
Follow manufacturer instructions regarding service.
Instructions for how to calibrate ECG machines will be provided by the manufacturer. Regular calibration is essential to ensure accurate readings.
Looking for an ECG Machine for Sale?
The ECG is one of the most important inventions and most useful tools in modern medicine. Medical and Surgical Centers use ECG machines because they are non-invasive and quickly administered. Patients experiencing chest pain or are thought to be experiencing a heart attack can easily be monitored and evaluated by using an electrocardiogram.
With a wide range of options, medical and surgical centers can choose an ECG machine with specific capabilities, configurations, and options.
