Cardiac Conduction Study.

  • SA: Sinoatrial node
  • AIT: Anterior internodal tract
  • MIT: Middle internodal tract
  • PIT: Posterior internodal tract
  • BB: Bachmann’s bundle
  • AV: Atrioventricular node
  • BH: Bundle of His
  • RB: Right bundle branch
  • LB: Left bundle branch
  • CP: Conduction pathways

In order to produce an efficient contraction to pump blood, the heart relies upon its electrical conduction system to synchronize its actions between the four chambers.

CS: Coronary sinus
RA: Right atrium
O: Oblique vein of left atrium
SC: Small cardiac vein
MC: Middle cardiac vein
LPV: Left posterior ventricular vein
LM: Left marginal vein
GC: Great cardiac vein

Why It’s Insanely Easy to Hack Hospital Equipment

When Scott Erven was given free reign to roam through all of the medical equipment used at a chain of large midwest health care facilities, he knew he would find security problems with the systems — but he wasn’t prepared for just how bad it would be.

Compact and elegant, it’s the perfect amount of liquid for one or two glasses. This makes the ceramic jug perfect for the home or office and for sharing simple yet intimate moments.

'Heart sock' could replace future implantable defibrillators

Implantable defibrillators and pacemakers have been around since the 1970s, but advances in materials science and 3-D visualization are transforming them from cumbersome life-support tools into streamlined therapies that could be props from Iron Man.

Smart skin patch knows when you need your meds

Researchers from South Korea have laid the groundwork for a dermal patch that not only dispenses medication continuously, but also knows when to stop.

A two-inch long patch made of stretchable nano-material, it can monitor muscle activity and body temperature. Current practical applications for the patch include drug delivery in patients with Parkinson’s disease, where muscle contractions and tremors can trigger medication release.

The researchers hope that in the future, more functions like wireless connectivity for remote monitoring can be achieved as the technology matures. The researchers estimate that the patch will not be ready for consumer use for another five years.
