What current ICD capacitor technologies provide the Tantalum Electrolytic
highest energy density and does not require
reformation?
1.67 Hz would equal how many bpm? 100 bpm
1 bpm = 0.0166667 Hz
, Which pace/sense lead designs would one expect the Brady lead w/ anode of 4.2 mm2 and cathode 5.2 mm2
highest current density w/ a bipolar impedance reading
of 1100 ohms?
What is the voltage measurement of a pacing system w/ V = 2.5 V
impedance of 500 ohms, current of 5.0 milliamp and
pulse width of 0.4 ms and rate of 60 bpm? V=I x R
= 5.0 milliamps x 500 ohms
= 2,500 millivolts
=2,500/1000
What condition is shown to have an increase stimulation Hyperkalemia (high potassium)
threshold, wide QRS, latency, or under sensing?
What is the estimated battery longevity of a pacemaker Longevity = 114 x (amp-hours/microamp drain)
with 1.0 amp-hour battery and 20 microamp drain ? = 114 x (1.0/20)
= 5.7 years
Which sensing related parameter represents the Slew rate
maximal rate of change of the electrical potential
between the sensing electrode and is the first
derivative of the electrogram?
The isovolumetric time from electrical depolarization of Pre-ejection interval
the heart to mechanical systole describes what term?
What test is typically performed during exercise with Micro volt t-wave alternans
HR around 105-115 and was shown to have a negative
predictive value in MADIT II and SCD-HeFT?
Which battery chemistry is now incorporated into Lithium silver vanadium & lithium carbon mono fluoride
pacemakers?
What test is performed over 10-20 beats following a Micro volt t-wave alternans
PVC and whose absence is a predictor of cardiac
mortality following an MI?
Fluoroquinolones, a new gen antibiotic is known for Prolonging QT
which cardiac effect?
What would decrease stim thresholds and current Reducing electrode surface area
drain? Ex: from 12mm to 8mm
Match the units: watt-second Power
Defibrillation energies exceed pacing energies by a 1,000,000
factor of ?
A band-pass filter modifies incoming signals according Hertz
to which of the following units of measure?
AV block occurs in what percentage of congenital 1-3%
open heart surgeries?
