AI Thread Summary
The discussion centers on an innovative EKG feedback device designed to enhance cardiac care by integrating diagnostic and therapeutic functions. This device features an elastic array of EKG sensors positioned around the chest to assess three-dimensional cardiac potential and includes high-voltage electrodes for potential treatment. It aims to improve survival rates for cardiac emergencies by at least 10% and reduce misapplication of defibrillators in public settings. The device is intended to operate under the supervision of a microprocessor to monitor resuscitation efforts. Comparisons are made to existing technologies, noting that while similar devices have existed since the 1960s, the proposed device could offer advantages without the complications of surgical implantation. The conversation also highlights the ease of training individuals to recognize cardiac fibrillation using minimal electrodes, emphasizing the potential for improved diagnostic accuracy with an electrode array.

EKG feedback "defibrillator" - public domain

Imagine placed around the chest, with an array of EKG sensors, a band of fabric positioned for determining a three-dimensional cardiac potential. Now consider this elastic array not only to diagnose immediate specific pathologies, but also to treat them with critically situated high voltage electrodes for applying a restoring potential. (The electrodes would be isolated enough from the current surge to avoid damaging their sensitive electronics.)

The type of resuscitation dispensed, if any, would be monitored by microprocessor. I believe the survival rate for those needing cardiac assist would increase at least 10% with my invention! Defibrillators are being installed in many public places, and this device would prevent much misapplication in situations involving possible heart failure. You heard it from me first!

My uncle had a defibrilator surgically implanted. Saved his life more than twice. It also nearly killed him a couple of times (going off while he's on the stairs, in the shower, etc.) but only in cases where he would have died for certain without it.

Sounds like your device could do the same thing without the complications of surgery.
 
A device similar to that which you describe was available going back at least to 1965. It was not used to trigger a defibrillation pulse, but an external cardiac pacemaker pulse. I may be wrong but conceptually I see little difference.

It’s really not difficult to train someone to diagnose fibrillation, as it is distinct from the normal cardiac rhythm as seen on an EKG (ECG). It requires only 2 electrodes to do so; the external defibrillator paddles serve the purpose. An array of electrodes is necessary for a well-trained physician to locate a specific diseased area of the heart and make a definite diagnosis. Electrically the heart can be considered a radiating dipole. An electrode array can provide positional information, as damaged tissue will cause a deviation from the norm.

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
