    Treatment for Third Degree Heart Block

    • Pacemaker
      • Battery lifespan is 10-15 years
      • Cheapest option is 1.8 million (assuming Philippine pesos)
      • Connected to the SA node, delivering electrical impulses to the heart, providing automatic rhythm control

    Understanding ECG

    • R represents the beginning of measurement so if an R wave is present you don't count the box it's on.
    • Small box: 0.04 seconds or 40 milliseconds
    • Big box: 0.20 seconds or 200 milliseconds
    • You don't count the box where the R wave is in, but you count the boxes after it.
    • Heart rate = number of R waves x 10
