Most likely you will have expired or cheap electrodes. Even if they stick to the patient there still may not be enough moisture in the electrode to conduct a signal. Either that or some of the lead wires may be damaged. All it takes is one intermittent lead to cause the problem you are asking about. The best thing to do is to start with he electrodes and then try the leads.

With leads hook correctly machine contuines to flat line


Check your RL (green) lead or trunk cable.

Right leg is the ground so (if it's bad) you won't get a QRS complex.

New Contec ECG 300EG model no tracings appear on the EKG paper.


Ekg machines print on thermal paper, This means that the impression is made by the print head heating the paper. If the print head is not making contact with the paper, you will get a faint tracing or no tracing at all. This needs to be adjust by a technician. Contec is located in China and we are a dealer. If you need their info or want us to look at it for you (for free) simply give us a call

My AT-2 plus EKG suddenly stopped transmitting from the electrodes, i.e. all the leads show flat line. My e-mail is alaronov@mac.com


hi,
You have to check the patient cable of you machine first. you have to check the LF (left foot ) lead of the cable. if there is any other cable you can try it with that. if there is any other ecg machine you have which has the same connector. then try with that also. if the cable found faulty then replace it. Is there is any trace ( line trace ) in the paper for lead 1 to v 6 if not , the problem is with thermal printer of you machine. if so you have to contact the nearest schiller authorized service center. Because the thermal printer head is not available in the open market.
ok

I just bought a unit AT2plus Schiller, and am having problems with the performance of the ECG. The ECG trace is getting too thick, making the visualization and interpretation. The change is seen in all...


There is a process for cleaning the print head. Try that first. I did a quick read of the manual, and it appears filters CAN be adjusted, but I would regard that as a last resort solution.

Also, adjust trace height (mm/mV) and paper speed to spread out the trace.

Lower half or EKG would not print properly


You should purchase a printer kit. This is a common problem I have encoutntered on this machine and this machine is identical to the Seca CT6I. I have ordered the printer kit from Seca in the UK, the part number is 9740490024 at a cost of £70. It is a straightforward repair.

EKG help


Using an EKG allows doctors to measure the relative voltage of these impulses at various positions in the heart. Electrocardiograms are possible because the body is a good conductor of electricity. When an electrical potential is generated in a section of the heart, an electrical current is conducted to the body surface in a specific area. Electrodes attached the body in these areas enable the measurement of these currents. On the handheld EKG machine, when your thumbs are in contact with the dry electrodes, the palm-sized device is able to trace and record the micro-current your heart generates during heartbeats, generating the related heart function parameters (PR, QRS, ST).

EKG Problem


EKGs provide useful data and can help detect various problems related to heart function. One basic determination that can be made with an EKG is the heart rate, which can be determined by measuring the distance between peaks. Diagnosis of certain medical problems is also possible. For example, in patients with high blood pressure, the amplitude of the QRS complex is significantly increased. The balance of certain chemicals in the body can also be detected by an EKG, since the amplitude of the signals is related to the levels of chemicals in the body. Damage in the heart can also be observed by a deformation in the Q wave. The most useful characteristic of the EKG is its ability to detect and describe arrhythmias, or abnormal heartbeats. EKG machines known as Holter monitors are for these detections. Finally, EKGs can be used to observe obstructions in the arteries. This is typically done by looking for a depressed segment between the S and T waves.
