<![CDATA[ The Frog sign refers to visible, prominent jugular venous pulsations in the neck that resemble the throbbing of a frog’s throat. Cause: It is typically seen in atrioventricular nodal reentrant tachycardia (AVNRT), a type of supraventricular tachycardia (SVT). Mechanism: During AVNRT, atrial and ventricular contractions occur simultaneously due to the reentry circuit in the AV node. This causes the atrium to contract against a closed tricuspid valve, leading to cannon A waves in the jugular vein — these produce the characteristic frog-like neck pulsations. Clinical Features: Sudden onset of palpitations Neck throbbing (“frog sign”) Rapid regular pulse Dizziness or syncope (sometimes) Diagnosis: ECG shows narrow QRS complex tachycardia (typical AVNRT). Jugular venous pulse (JVP) reveals cannon A waves. Treatment: Vagal maneuvers (e.g., Valsalva, carotid sinus massage) Adenosine (drug of choice) Beta-blockers or calcium channel blockers Radiofrequency ablation for recurrent cases ]]>

<![CDATA[ Romberg Sign ]]>
</video:title>
<video:description>
<![CDATA[ 🧠 Romberg Sign Definition: The Romberg test assesses proprioception — the body’s sense of position in space — which depends on dorsal column function of the spinal cord. How to perform: Ask the patient to stand with feet together and arms by the side. First with eyes open, then eyes closed. Observe for swaying or loss of balance. Interpretation: ✅ Negative Romberg sign: Patient remains stable with eyes closed → normal proprioception and vestibular function. ⚠️ Positive Romberg sign: Patient stands steadily with eyes open but sways or falls when eyes are closed → sensory ataxia (loss of proprioception). Indicates: Lesion of dorsal columns or sensory pathways (not cerebellar). Causes of positive Romberg: Tabes dorsalis (neurosyphilis) Vitamin B12 deficiency Peripheral neuropathy (diabetes, alcoholism) Posterior column disease Key Point: 👉 Cerebellar ataxia causes unsteadiness even with eyes open, so Romberg test is not positive in cerebellar lesions. 💪 Pronator Drift Test Definition: The Pronator drift test detects subtle upper motor neuron (UMN) weakness and corticospinal tract lesions. How to perform: Ask the patient to extend both arms forward, palms up, eyes closed. Observe for 30 seconds. Interpretation: ✅ Normal: Both arms remain steady. ⚠️ Positive Pronator drift: One arm pronates (palm turns downward) and drifts downward — indicates contralateral corticospinal tract lesion. Variants: Upward drift → cerebellar lesion (with outward movement). Downward + pronation → pyramidal (UMN) lesion. Indicates: Lesion in motor cortex or corticospinal tract (commonly in stroke, multiple sclerosis, brain tumor). ]]>
