Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to see whether individuals who access the "911" emergency medical system with a heart attack or severe chest pain will receive more timely hospital treatment and better outcomes if hospital clinicians are provided with earlier and more complete electrocardiography (ECG) information.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase III study. Patients will be randomized (like tossing a coin) to 1 of 2 groups: Group 1: Patients will have pre-hospital ECG intervention. Group 2: Patients will have routine emergency heart care. Information will be collected about time symptoms started, clinical management, and other measures. All patients will be contacted by telephone 12 months later and interviewed as to whether they experienced any cardiac symptoms.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Electrocardiogram (ECG) Intervention

Patients randomized to the experimental group had their ECGs printed out in the target ED with an audible voice alarm. Print-out of the pre-hospital ECG in the target ED was the intervention.

Group Type EXPERIMENTAL

Electrocardiogram (ECG) Intervention

Intervention Type DEVICE

Pre-hospital electrocardiographic (ECG) monitoring with special software to detect myocardial ischemia and to automatically transmit an ECG to the destination hospital emergency department with a voice alarm announcing "Incoming ECG from the field" and print out in the ED.

Routine Clinical Practice

Control patients had an ECG conducted after hospital arrival, as was the standard of care in the county.

Group Type OTHER

Routine Clinical Practice

Intervention Type OTHER

ECG in the ED as part of routine clinical practice.
