Background:
Germany was the first country worldwide to issue a directive regulating the provision of automated external defibrillators (AEDs) on board merchant ships.
Aims:
To test the applicability and suitability for telemedicine in seafaring, including long-term electrocardiogram (ECG) monitoring, of three currently available AEDs.
Methods:
Sixty nautical officers were asked to record and transmit a one-lead ECG with one of three AEDs under test. Subsequently, they evaluated the user-friendliness of the devices.
Results:
The number of steps required for ECG transmission (as a pdf file) varied from three to six between the various AEDs. Correspondingly, differences were found in the subjects' understanding of the AED software. After theoretical instruction in the use of the AEDs, 55 officers (92%) succeeded in telemedical transmission of the pdf file without any help. At the time of our investigation, long-term ECG monitoring was possible with only one of the AEDs.
Conclusions:
The study results suggest that most trained lay rescuers can use conventional AEDs effectively for ECG transmission.

This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
