Sinus rhythm
In normal sinus rhythm the heart rate is below
Heart rate of lions ranged from 42 to 76 beats per minute (bpm). Heart rate of tigers ranged from 56 to 97 bpm. In both species, the most common rhythm detected was normal sinus rhythm followed by sinus arrhythmia; wandering pacemaker was also observed with normal sinus rhythm or sinus arrhythmia.

That's normal for hedgehogs...
Yes, sinus rhythm can be pulseless in certain conditions, such as in cases of severe hypotension or cardiac arrest. While sinus rhythm indicates that the heart's electrical system is functioning normally, it does not guarantee effective blood circulation. If the heart is not generating sufficient contraction strength or if there is severe obstruction in blood flow, a person may have a sinus rhythm without a detectable pulse. This condition requires immediate medical intervention.
When the heart is functioning properly the sinus node controls the firing of action potential that contract the heart. When the sinus node dominates the heart will contract in a synchronized and effective rhythm This is called sinus rhythm.
Sinus rhythm of 48-112 beats per minute (BPM) indicates that the heart is beating in a regular pattern initiated by the sinus node, which is the heart's natural pacemaker. A rate of 48 BPM is considered bradycardia (slow heart rate), while 112 BPM is considered tachycardia (fast heart rate). This range suggests that the heart is functioning normally, but the specific rate can indicate different physiological states or conditions, such as physical fitness, stress, or underlying health issues. It's important to interpret this in the context of the individual's overall health and symptoms.

Sinus nodes (sa nodes)
Underlying sinus rhythm refers to the normal heart rhythm generated by the sinoatrial (SA) node, which is the heart's natural pacemaker. It is characterized by a consistent pattern of electrical impulses that result in a regular heartbeat, typically at a rate of 60 to 100 beats per minute. This rhythm is essential for maintaining effective blood circulation and is typically assessed through an electrocardiogram (ECG). Abnormalities in the underlying sinus rhythm can indicate various cardiac conditions.
Normal Sinus Rhythm is the normal beating of the heart. The adult heart rate is between 60-100 beats per minute and regular. Slower heart rate is called bradycardia and faster heart rate is Tachycardia.
