Clinical characteristics between patients with low and high burdens of ventricular pacing.

<p>Clinical characteristics between patients with low and high burdens of ventricular pacing.</p

Examples of normal and abnormal polar plot strain maps.

<p>(A) Normal polar plot map (GLS -20%). (B) Abnormal polar plot map from a patient who developed PICMP by 12 months. GLS and TPS-SD measure -12% and 75ms respectively, indicating reduced global longitudinal strain and LV dyssynchrony.</p

Global longitudinal strain analysis.

<p><b>(A)</b> pre pacemaker implant, <b>(B)</b> one-month after the initiation of pacing in a patient who developed PIVD and <b>(C)</b> 12 months after pacing in a patient who went on to develop PICMP.</p
