Summary
A new smartphone app, SMART AMI-ACS, improves communication for ST-elevation myocardial infarction (STEMI) activation. This technology enhances decision-making, leading to faster treatment and better patient outcomes in acute coronary syndromes.
Area of Science:
- Digital Health and Medical Informatics
- Cardiovascular Medicine and Interventional Cardiology
- Health Services Research and Implementation Science
Background:
- Timely diagnosis and treatment of ST-elevation myocardial infarction (STEMI) necessitate coordinated provider response and rapid intervention.
- Current STEMI activation protocols involve verbal communication and secure sharing of electrocardiographic (ECG) images, with opportunities for improvement.
- A novel, privacy-compliant smartphone application, SMART AMI-ACS, was developed for real-time communication and ECG sharing among healthcare providers in Ontario, Canada.
Purpose of the Study:
- To integrate the SMART AMI-ACS app into clinical workflows to optimize STEMI activation communication.
- To decrease treatment times and improve patient outcomes through enhanced communication.
- To reduce unnecessary cardiac catheterization laboratory activations and transfers.
Main Methods:
- Study implementation guided by the Reach, Effectiveness, Acceptability, Implementation, and Maintenance (RE-AIM) framework.
- Utilized quantitative registry data (SMART AMI project), app usage data, and quantitative/qualitative survey data from physicians.
- Employed interrupted time series regression models for outcome evaluation, alongside descriptive and thematic analyses.
Main Results:
- Primary outcomes focus on app usability, acceptability, and functionality, assessed via electronic surveys.
- Key outcomes include evaluation of timing-of-care intervals, false catheterization laboratory activation rates, and physician app uptake.
- Prospective evaluation period: April 1, 2022 – March 31, 2023; registry data comparison: January 1, 2019 – March 31, 2023.
Conclusions:
- Smartphone technology offers a secure, accessible platform for clinical practice integration.
- The SMART AMI-ACS app leverages smartphone accessibility for efficient and secure information transmission.
- Emergency medicine physicians can utilize the app for rapid, secure, and accurate decision-making in STEMI activation.

01:29Electrocardiogram
2.2K
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and...

01:30Pulse rhythm
775
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Introduction
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

An electrocardiogram (ECG)graphically represents the heart's electrical activity on ECG paper or a monitor.
Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage....

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

01:30Cardiac Action Potential
1.1K
Cardiac action potentials are essential for proper heart function, enabling the rhythmic contractions needed for adequate blood circulation. Nodal cells and Purkinje fibers, specialized for electrical conduction, generate these action potentials.
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
