Abstract
A mobile electrocardiogram ECG transmission system was developed which could transmit single lead ECG data via GSM mobile telephony Ambulance transmission trials comprised a total of 72 communications of which 94 were successful The system was able to redial up to a predetermined number of times until the GSM call was re established during the trials this value was set to five The average number of GSM call tries was 1 3 per connection The mean time required to establish a connection was 45 s the minimum was 34 s when only one attempt was needed to establish a GSM call The average duration of ECG transmission between communication breakdowns was 5 min 12 s When a link breakdown occurred the user had to wait for an average of only 42 s to continue monitoring the signal
