In one embodiment, an ablation system includes a probe to be inserted into a heart and including an electrode to apply radiofrequency (RF) power so as to ablate a myocardium, an RF signal generator, a tracking module to compute a relative location and orientation of the probe, and a processor to receive a signal from at least one user input device indicating an actuation of a serial ablation procedure including performing ablations at different locations of the myocardium, and control the serial ablation procedure so that for each ablation the processor is configured to check whether the relative location and orientation of the probe are steady, automatically compute an ablation duration, automatically control the RF signal generator to generate the RF power for the computed ablation duration, and render a user interface screen including a time indicator indicating a time remaining until an end of the ablation duration.
