Ease of Use of the PACE® Series

Application-oriented technology

Smart Innovations

Osypka Medical`s temporary cardiac pacemakers, the PACE® Series, are each made with the user in mind. Taking into account years of end-user feedback and technological advances, Osypka Medical has incorporated simple and intuitive improvements in the PACE® Model 101, PACE® Model 203, and PACE® Model 300, that makes conventional temporary pacing effortless.

Device design and medical education training are key points towards becoming comfortable in the safe and effective use of a temporary pacemaker.

Simple Measurement of P/R Wave Amplitudes

Simple Measurement of P/R Wave Amplitudes

The sensing threshold for P waves (atrium) or R waves (ventricle) is illustrated as a “fence line” below which all P waves or R waves, respectively, are not visible to the pacemaker.

Sensing thresholds are usually set between 1/2 and 1/3 of the P/R wave amplitudes – which requires measurement of the intrinsic P/R wave amplitudes while the pacemaker is inhibiting.

PACE® Model 203 and PACE® Model 300 measure and display P/R wave amplitudes – as well as atrial and ventricular heart rate and the AV Interval – upon pressing the PAUSE key. Note pressing the PAUSE key is inhibiting pacing for up to 10 seconds.

This feature will make you become more comfortable in dealing with sensing thresholds – when setting up the pacemaker as well as intermittently during therapy!

AUTO SENSE

The AUTO SENSE function measures intrinsic P/R amplitudes and automatically adjusts the atrial and/ or ventricular sensing threshold, considering 2/3 safety margin (sensing threshold = 1/3 of P/R amplitudes).  Thus, manual measurement and readjustment of the sensing thresholds become redundant, when intrinsic P/R waves are regularly present.

Impedance

Impedance

Electrical impedance (or resistance) measured in Ω (Ohms) describes best the electrical properties of the stimulation circuit – that is, the extension cable, the pacing lead and the tissue.

Like many things in life, impedance shall stay within a normal range (200 Ω to 1,000 Ω) and not exceed this range in either direction.

Low impedance may be caused, for instance, by unipolar pacing wires placed in proximity (atrium!) or by large “naked” electrode surfaces. A short-circuit is the most extreme care of a low impedance situation.

High impedance is caused by pacing leads with poor electrical tissue contact or connection issues.

PACE® Model 203 shows the measured impedance as well as the set pacing amplitude (in Volts) and the measured stimulation current (in mA) any time the atrial or ventricular output dial is turned – even when the device is locked.

PACE® Model 300 has the impedance function implemented in its submenu.

This feature will give you a peace of mind – and assist in trouble shooting if unable to obtain capture!

Statistics

Statistics

Ever wondered whether, in retrospect, the patient was depending on the pacemaker or was on its own rhythm?

PACE® Model 203 counts intrinsic and paced cardiac cycles, and much more. Considering this statistical supports the decision making towards further therapy needs.

Operating Controls

Operating Controls
  • Dials on PACE® Model 203 and Model 300 are arranged in the order of the electrical conduction system of the heart.
  • Color coding supports distinction between atrial (blue) and ventricular (white) controls, ideally in combination with color-codes temporary pacing leads/wires.
  • Single key press to switch between dual-chamber and single-chamber pacing modes.
  • Transition from synchronous to asynchronous pacing modes simply via increasing the sensing threshold(s).

Automatic Adjustment of Pacing Parameters

Automatic Adjustment of Pacing Parameters

In DDD or DDD-BV pacing modes, atrioventricular delay (AVD), post-ventricular atrial refractory period (PVARP) and maximum tracking rate (MTR) are dependent on the basic pacing rate.

Upon turning on PACE® Model 203 or PACE® Model 300, AVD, PVARP and MTR are conveniently modified automatically based on the set basic pacing rate (indicated in the display by an AUTO sign).

Custom Configuration upon Turning On

PACE® Model 203 and PACE® Model 300 allow customization of the pacing mode and the pacing parameters present upon turning on the device.

Standby Mode

PACE® Model 203 and Model 300 may be turned off temporarily and resume the previous pacing therapy upon turn-on.

Acoustic and Optical Signals

Intrinsic P/R waves (exceeding the “fence line” established by the respective sensing thresholds) and pacing pulses are indicated visually and acoustically.

Connection Variants

Connection Variants

PACE® Model 101 and PACE® Model 203 are offered either with bipolar terminals or receptacles which accept pins with a diameter of 0.9 … 2.0 mm (think: pacing wires).

Battery Lifetime

Our pacemakers are optimized for a long battery life (PACE® Model 101 for up to 38 days, constantly pacing!).

Towards the end of battery life, a two-step indicator reminds you in time you to replace the battery.
