Brief Summary: This is an observational registry study aiming to collect data on efficacy and safety of the single chamber Biotronik DX system with enhanced atrial diagnostics. The minimal follow-up period is 24 months. All analyses on the data will be done post-hoc; the study does not intend to confirm any pre-specified hypotheses.
Detailed Description: Enrollment (E0)

Timing:

• The enrollment (date of patient written informed consent) starts after implantation of a BIOTRONIK Lumax 540 VR-T DX ICD with Linoxsmart S DX or successor single chamber DX system according to current guidelines (primary or secondary prevention) but should not be later than 90 days after implantation.

Procedures:

* Check inclusion and exclusion criteria
* Patient information and written informed consent process
* Assignment of a unique study code
* ICD interrogation (re-programming if necessary)
* HMSC registration (recommended)
* Investigator assessment: appropriate atrial sensing

Documentation (note: where available the most recent assessment recorded within six months prior to hospital discharge shall be considered):

* Medical History:

* Demographic data
* General history of cardiovascular disease
* Etiology of underlying heart disease
* Cardiac events and symptoms
* Documented supraventricular arrhythmia prior to implantation
* Device Interrogation

* Date, home monitoring function, MRI scan
* AF history:

* type (none, paroxysmal, persistent, permanent)
* date of first diagnosis (if applicable)
* EHRA classification (if applicable)
* AF burden (if available)
* CHA2DS2-VASc
* Risk factors and comorbidities:
* thyroid dysfunction
* diabetes mellitus
* COPD
* sleep apnea
* chronic renal disease
* History of thromboembolic events or stroke
* Physical Examination:

* Vital signs (SBP, DBP, height, body weight, BMI)
* Current medication (substance class)
* Heart failure indices
* NYHA classification
* BNP and NT-proBNP (only if determined in routine clinical practice)
* LVEF (optional; echocardiography preferred, other methods accepted if no echo available)
* ECG parameters (12 lead ECG; optional)
* RR, PQ, and QT intervals
* QRS width
* rhythm disorders
* clinical findings, morphology
* Implantation:

* Indication (primary prevention, secondary prevention)
* Type of procedure (first implantation / replacement)
* RV lead:
* Dislodgement / repositioning after implantation?
* Sufficient amplitudes (Atrial; Ventricular) and thresholds (Ventricular)
* Other clinical complications during / after implantation?
* Final lead position at discharge (apical, septal, other)
* Atrial dipole (with or without atrial wall contact at rest)
* Ease of implantation as assessed by investigator
* An extended questionnaire including more detailed information on implantation procedure, technique and initial measurements will be requested as an optional documentation where data are available

Follow-up Y1 and Y2

Timing:

• 12 and 24 months (+/-2 months) after enrollment respectively

Procedures:

* ICD interrogation / function check-up and re-programming if necessary
* Programmer download of all data not yet submitted to BIOTRONIK according to current working instruction
* Investigator assessment: appropriate atrial sensing

Documentation (note: where available the most recent assessment recorded between the current and the preceding visit shall be considered):

* Physical Examination:

* Vital signs (SBP, DBP, height, body weight, BMI)
* Current medication (substance class)
* Heart Failure indices:
* NYHA classification
* BNP and NT-proBNP (only if determined in routine clinical practice)
* LVEF (optional; echocardiography preferred, other methods accepted if no echo available)
* ECG parameters (12 lead ECG; optional):
* RR, PQ, and QT intervals
* QRS width
* rhythm disorders
* clinical findings, morphology
* Device Interrogation

* Date, home monitoring function, MRI scan

Event based documentation

* New-onset or worsening AF
* AF interventions
* Worsening heart failure
* Shock episode
* Thromboembolic events (CVA, TIA, PAE)
* Continuous surveillance / reporting of (serious) adverse events / (serious) adverse device effects
