An ultrasound transducer unit (), e.g. probe, is configured with a friction guiding function. The transducer unit () comprises a vibration generating means () at a tissue contact area, and has means for sensing a sliding direction of the transducer unit across a tissue surface () at which the contact area is incident. The tissue surface may be an external skin surface or an internal tissue surface, e.g. in case of a catheter. A control means is operable to control the vibration of the vibration generator to adjust a level of friction at the tissue contact area. This is used by the control means to implement a friction guiding function for guiding a user in sliding the unit across the incident surface, e.g. toward a target location (), based on controlling the friction level responsive to sensed sliding direction, for instance providing lower friction when sliding is in a target direction, while leaving other directions with relative higher frictional resistance.

A method and a device for classifying cardiac arrhythmia, using an electrocardiogram (ECG) signal, are provided. The method includes receiving the ECG signal representing an electrical activity of a heart of an individual over a period of time, the ECG signal including ECG beats. The method further includes converting each of the ECG beats into symbols. The method further includes identifying an arrhythmia class indicating a type of cardiac arrhythmia associated with the individual from arrhythmia classes indicating respective types of cardiac arrhythmia based on the symbols representing each of the ECG beats.
