Simultaneous Atrial/Ventricular Electrocardiogram Diagnostics
Funding By: Rady Children's Foundation, Academic Enrichment Grant"
Sponsored by Dr. James Perry M.D.
Background:
The hearts of children at the Rady's Children's Hospital who undergo cardiac surgery are monitored carefully and intensely as complications can arise after the surgery. A standard ECG is used on patients in order to monitor the heart's beating patterns and many patients have a temporary pacemaker connected to the patient's heart through epicardial wires that are placed on specific places of the patients heart. However, if there is an irregularity with the patient's heart that the ECG alone cannot discern, the temporary pacing wires must be removed from the temporary pacemaker and placed into a separate machine that is able to provide what is known as an Atrial Electrocardiogram or Ventricular Electrocardiogram. From this newly developed waveform, doctors can diagnose the patient's condition and then use the temporary pacemaker to the treat the condition. This requires the hospital staff to then disconnect the temporary pacing wires from the ECG machine and back into the temporary pacemaker where the patient can then be treated. This process, from realizing the problem, to diagnoses, and then to treatment, may take from 3-5 minutes to accomplish. These are critical seconds to the patient's survival rate and the electrocardiogram hub aims to decrease the time between problem to treatment.
Objective:
The objective of the electrocardiogram hub is to reduce the time of diagnosis and treatment of pediatric patients who may suffer from complications after cardiac surgery and to simplify the lives of the hospital staff. The electrocardiogram hub will be able to display the critical Atrial electrocardiogram and Ventricular electrocardiogram along side the usual Electrocardiogram signal, while eliminating the need for the temporary pacing wires to be disconnected from the temporary pacemaker. This will allow the doctor to diagnose and treat the patient immediately after a condition arises which will increase the survival rate of the patient undergoing the episode.
3. Inside the Hub, a Signal Conditioning PCB conditions the signals before being inputted into the myRIO
2. Epicardial Temporary Pacing wires are connected to the Hub
1. Left Arm, Right Arm, and Right Leg Electrode Signals are spliced using an adapter and fed into the hub's myRIO computer
How It Works
Deliverables:
1. Uphold patient safety
2. Display AEG/VEG waveforms along with ECG to Tablet Device
3. Maintain connection between Temporary Pacing Wires and Temporary Pacemaker without disturbing pacing signals
4. Offer temporary storage of patient data
4. Hub's myRIO computer is fed signals from the Signal Conditioning Board and creates the waveforms
5. Waveforms are sent wirelessly to a Tablet using National Instrument's Data Dashboard App
6. Epicardial wires remain connected to the temporary pacemaker throughout
