The invention relates to a cardiac ablation or mapping catheter with a rotatable head end in the technical field of cardiac ablation. The cardiac ablation or mapping catheter comprises a catheter body, an adjusting inner tube, a control handle and the head end. The control handle is located on the tube body, the adjusting inner tube penetrates through the tube body, and the head end is connected with the adjusting inner tube. A rotating mechanism and an adjusting knob are arranged in the control handle; the head end comprises an electrode tip consisting of n electrode arms; the electrode tip comprises an adjustable electrode arm and a non-adjustable mechanical arm, one end of the mechanical arm is connected with the adjusting inner pipe, and the other end of the mechanical arm is connected with the guide cap. The electrode can be in full contact with the heart wall and can also enter pulmonary veins and other lumen parts to be effectively attached, so that the electrode density is kept, and effective ablation
