Fix bug preventing opening links to source references

App Description

This app collects over 30 published formulas for calculating the corrected and predicted QT interval (QTc and QTp). Included are details on each formula and reference links. Results are analyzed statistically and graphed. Published definitions of normal and abnormal QTc intervals are also included.

This is no ordinary calculator that just gives you the results of Bazett's formula. If you are interested in this fascinating corner of electrocardiology, this app is for you.
