Developed specifically for ECG and blood pressure (BP) testing in companion animals features an external six-lead ECG module and an external BP module. With the ECG module plugged in, the Unit works as a diagnostic six-lead ECG system (the picture on the left). With the BP module plugged in, the Unit works as a diagnostic BP monitor (the picture on the right). The Unit is not designed to use both modules at the same time, i.e. the Unit can not do ECG and BP testing simultaneously. You can choose to purchase the Unit with both of the modules, only the six-lead ECG module, or only the BP module, and add the other module later at any time.. Compatible with ALL Practice Management Software Systems The Unit automatically and continuously saves all ECG tracings or BP readings on a regular USB flash drive. Simply take the flash drive to your computer to transfer the saved data, which is compatible with AVIMark or any other system you may have. Diagnostic Six-lead ECG The Unit simultaneously records six Leads of ECG (Lead-I, Lead-II, Lead-III, aVR, aVL, and aVF), and automatically and continuously saves all registered ECG on the USB flash drive, which can be reviewed on your computer with the included VetSpecs® software. The ECG data can then be integrated into your patient database under your practice management system. You also can transfer the ECG data to any computers, email to anyone you want, and print in standard diagnostic format on regular plain papers through any office laser or ink-jet printer.
