Comparative spatial resolution of 12-lead electrocardiography and an automated algorithm.

Background: The spatial resolution of pacemapping using 12-lead electrocardiography (ECG) or PaSo software is unknown.

Objective: The purpose of this study was to determine the spatial resolution of traditional ECG pacemapping and pacemapping using the PaSo coefficients.

Methods: Seventeen patients undergoing ablation of supraventricular tachycardias or atrioventricular node were included.

Refugia under threat: Mass bleaching of coral assemblages in high-latitude eastern Australia.

Environmental anomalies that trigger adverse physiological responses and mortality are occurring with increasing frequency due to climate change. At species' range peripheries, environmental anomalies are particularly concerning because species often exist at their environmental tolerance limits and may not be able to migrate to escape unfavourable conditions. Here, we investigated the bleaching response and mortality of 14 coral genera across high-latitude eastern Australia during a global heat stress event in 2016.
