Your heartbeat is monitored throughout the procedure using an electrocardiograph machine. |
The electrocardiograph was among the earliest useful medical electronic instruments, having been coupled to an amplifier about 75 years ago. |
Mean QRS axis values were automatically calculated by the electrocardiograph. |
A direct writing electrocardiograph was attached, and I was offered the trace. |
Data from an onboard electrocardiograph machine will also be sent to hospitals. |
When a suspected heart attack victim arrives at the emergency department an electrocardiograph is carried out to confirm the condition. |
